ZOE HILL: If I collect just say a hundred grams of something,
that can be 2,000 future trees. In 20 years time I can collect
from those and those 2,000 trees can become 200,000 trees.
ROSIE HOLDSWORTH: Welcome to Wild Voices, a special series
from Wild Tales of inspiring conversations about people,
nature and the stories that connect us. It's often said that
trees are the lungs of the planet. And as the impacts of
climate change become increasingly visible, their
importance has never been greater.
In this episode of Wild Voices, Ajay Tegala is joined by Zoe
Hill, the National Trust's Tree Nursery Officer, to discover
what it takes to care for 50,000 tree saplings, how she's helping
to create a more climate-resilient landscape, and
what we can all do to help trees thrive.
AJAY TEGALA: Hello and welcome to another Wild Voices episode
of Wild Tales. I'm Ajay Tegala, Nature Communicator and National
Trust Ranger on Britain's very first nature reserve, Wicken
Fen, and today I'm experiencing another first. I'm in the studio
chatting with Zoe Hill, the National Trust's first and only
Tree Nursery Officer. Hi Zoe, how are you doing?
ZOE HILL: Yeah, not bad thank you. Yourself?
AJAY TEGALA: Very well, thank you very much. Very excited to
talk to you. And I thought I'd start with asking you really,
what is being a Tree Nursery Officer really like?
ZOE HILL: You know what, it's very unique, you know, my job
revolves so much around kind of what's going on in the
environment. You know, I spend a lot of my time kind of, I go
out, I propagate, I kind of grow on and I supply.
And so being able to kind of do that is just, it's one of the
most incredible jobs.
AJAY TEGALA: I gather you were a gardener before this so is that
where your propagation love began?
ZOE HILL: Yeah so I worked on a kind of semi-private estate
managing kind of 10 acres of grounds with the team and we did
a lot of annual bedding displays and when I was training we did a
lot of propagation on those and I kind of I just fell in love
with being able to just kind of create something from like one
specimen and so you know I kind of took that love of being able
to grow a couple thousand geraniums.
And then I saw a job for a Tree Nursery Officer and I was like,
wow, I can do that for trees too. And it kind of just like
got the cogs turning in my brain of being able to go like, okay,
I can propagate more and more things. And then I was able to
then place all these little different bits together.
AJAY TEGALA: And for people that may not be familiar with the
term propagation, how would you describe that?
ZOE HILL: I kind of describe it as a way of being able to
reproduce a plant. You can do it so many different ways. You can
do it by seed, you can do it by cuttings, you can do it with a
leaf. There's so many different ways to be able to propagate a
plant. It's almost, you know, it's like having plant babies in
a way.
You're able to then create kind of that genetic matchup of
material. You know, a lot of times you see the 50% of the
parent plant if it's a seed or, you know, you're taking 100% of
the genetic material if it's a cutting. And so you're able to
kind of directly pass on a lineage of a plant in a way.
AJAY TEGALA: That's amazing. Tell me about your office
because it's a tree nursery what does that look like?
ZOE HILL: My office so to speak is all outside I have a really
nice shade tunnel which enables me to grow a range of species
with a kind of certain level of protection. I have outdoor
growing beds which I can grow kind of in the region of 30,000
trees just out in the open in soil that we kind of work, we
manicure, we tailor to the trees we want to grow.
And then I also have like outdoor growing areas where I
have kind of specialised air pruning pots that we sow our
seed into and we can grow those out in those pots.
And that gives the rangers like a perfect way of planting those
saplings because they're so easy. They're kind of a one inch
cell that's maybe 20 centimetres long. They can take out a bundle
of 100 and plant really easily.
AJAY TEGALA: And how many trees are we talking about? What sort
of numbers are involved?
ZOE HILL: So in the nursery we went through this other day, we
currently have 41 different species of tree on site.
And currently we have 50,000 trees in the nursery. And with
that, we're talking maybe 20,000 of those going out this year and
then a further 20 going out next year. And kind of that revolving
cycle.
AJAY TEGALA: And are there any particular species that you
particularly love and that you're excited about?
ZOE HILL: See, it's... There's a bit of like, because I was
speaking to my volunteers about this the other day, and we were
all talking about like, oh, you know, trees you remember from
your childhood. And one none of us mentioned was spindle. And
yet in an environment now, we love spindle.
It's a tree, large shrub kind of thing. And this time of year,
it's got lovely pink fruits, which on the inside have the
orange kind of seeds. And it's just none of us can remember
seeing it as a child. And yet as an adult, they're just so
amazing.
AJAY TEGALA: I was the same. I think I first learnt it when I
was probably a teenager. Someone pointed it out. And it's great
for birds, isn't it? Great food source for them.
ZOE HILL: Yeah, it's just like... You know, you can see it
now. Every time you look in a hedgerow, you spot it, you know.
It's amongst the blackthorn, it's amongst the hawthorn, you
know. And it just, it stands out. It just catches your eye.
AJAY TEGALA: That's the lovely thing when you get to know more
species. You start to spot them, don't you, in the wild. Yeah.
But of course, with you propagating them and sort of
caring for them, that must be quite a big responsibility,
actually.
ZOE HILL: It kind of really is in a way, you know. You almost
really take ownership of them. Sometimes you think, okay, I'm
growing 3,000 of this. Even if you get kind of 10 that don't
happen to kind of succeed as well, there is this kind of
level of like, oh, really frustrating.
But also it's amazing because, you know, if I collect just say
100 grams of something, that can be 2,000 future trees. And then
I'll say, okay, we'll plant out those 2,000 trees. In 20 years
time, I can collect... From those and those 2,000 trees can
become 200,000 trees.
AJAY TEGALA: Yeah so you're playing a small but huge part
actually in history really with things that could live for well
hundreds of years to come potentially. Yeah. And so what
is perhaps one of the most precious seeds that you've
collected in your time?
ZOE HILL: I think it's probably going to have to go with some of
the white beams. I'm in an area where we don't particularly have
many and you know They're a little bit more on the kind of
pickier side to propagate.
I personally haven't managed to do it very well, but I know
there's people that specialise in it. Whitebeams have so many
cultivars as well. You know, we've got local ones to us like
odometer, which is named because it's a sorbus near a car park
meter, hence why it's called odometer.
And then you've got things like chedorensis, which is on the
Cheddar Gorge, which is just up the road from us. And so I'm
kind of trying to work with those and try and start
propagating those and it's almost like a challenge
AJAY TEGALA: Yeah yeah and this is obviously Somerset so that's
where you're based the Holnicote Estate?
ZOE HILL: Yes yes on Holnicote so Holnicote very unique you
know with 12 and a half thousand acres with almost like a mosaic
of habitat you know we've got salt marshes we've got temperate
rainforest we've got our riparian habitats, you know
we've got kind of coastland, heathland, you know I have the
most unlimited choice to go select our seed from.
AJAY TEGALA: Amazing. And so supplying them obviously for the
estate and for other people is how it works. Is there kind of
quite a wide audience of people these trees are going to?
ZOE HILL: So at the moment, we're just supplying our estate.
But as the nursery progresses through its kind of development
phases, the ambition is we'll start supplying some of our
wider Somerset properties, whether that's our Quantocks and
our Mendips or local kind of other National Trust sites. But
we're also working with our tenant farmers.
The hope is to start supplying hedging packs, fruit trees for
them to plant. And so we'll graft our fruit trees in the
nursery as well. And those will be from local varieties that we
can then kind of put out for our tenants to create orchards.
AJAY TEGALA: So it's fantastic there's these opportunities to
expand. But it's kind of mind blowing that actually for one
estate, there's this such a huge number of trees that you're
working with.
ZOE HILL: Absolutely. It's, you know, when we think about a tree
plant in this winter, we're talking one field. And we're
going to put in the region of 8,000 trees in there, it seems
like such a big number. Actually, when you look at it as
a scale, it's actually so small.
And, you know, over time, as we kind of produce more trees, it's
going to be amazing to see how those go out and not into just
our kind of our local environment, but into the wider
environment as well.
AJAY TEGALA: And so before your role came along, presumably the
Trust were sourcing trees from elsewhere, but then they
realised, actually, this is something that we can be doing
ourselves.
ZOE HILL: I'm going to speak from our property personally,
but you know, we were sourcing our trees from some of the other
local nurseries. And what we started to kind of think about
here was actually, where are they getting their trees from?
Sometimes these nurseries, whilst they do grow a lot
themselves, they unfortunately have to buy in their surplus.
And so there's kind of this like ongoing traceability for trees
that we thought was very important for us in kind of
knowing what we're planting is the best of what we could be
planting.
And so that kind of forwarded the movement for us to start
producing our own trees. There was also that carbon thinking
element. With growing trees you don't just think about the
carbon tax to grow them, but it's also kind of the getting
them to us as well.
AJAY TEGALA: And it's quite an incredible job that you're
doing.
But it's not something you do on your own, is it? I'm guessing
that volunteers probably play an important part in supporting
you?
ZOE HILL: Absolutely.
I couldn't do half the work I do without volunteers. We'll go
out, we'll collect seed together. And just that, you
know, we'll spend all day out between one or two woodlands
where we can collect five or six different species. Which we can
then bring back into the nursery. We'll then process all
together and then we stratify them together.
We sew them together. We do everything and they're involved
in the whole process, which I think they really enjoy because
it gives them also a sense of ownership in the kind of
environment that we're creating, not only inside the nursery, but
outside of the nursery as well.
AJAY TEGALA: And I suppose you've got to think about
disease and biosecurity. I suppose that's part of the
consideration as well.
ZOE HILL: Yeah, so that's kind of a big thing in the nursery.
So we're actually the first property in the Trust where our
nursery is plant healthy certified. And that means we've
almost gone above and beyond to become biosecure. It's really
important for us that coming into the nursery, we're not
bringing in any pest diseases or pathogens.
And so we have a very strict kind of cleaning our boots
procedure, making sure that our clothing is clean before we come
in. But we also take that out with us as well. If we go to
collect seed from one woodland, We want to ensure that our boots
are clean before we go in, our tools are clean before we go in.
So we're not spreading anything, not only between woodlands, but
then to and from the nursery either.
AJAY TEGALA: So when your day starts, your first job basically
is to clean your boots then?
ZOE HILL: Pretty much. So I actually have a dedicated pair
of nursery boots that do not leave the nursery. Just because,
you know, it's cleaning your boots every day. It's one of
those things that could slip your mind. And so I take that
error process out of the equation.
AJAY TEGALA: And I suppose biosecurity and not... The
spread of disease is even more of a consideration with climate
change. And so this year, having faced such a serious drought in
the grass, it's been obvious seeing that die and trees losing
their leaves so much earlier. Trees are so important to
combating climate change for so many reasons, aren't they?
ZOE HILL: Yes, yes, absolutely. They enable almost like a cooler
microclimate beneath them. And that not only helps the tree,
but also it helps all the ground floor and things as well.
AJAY TEGALA: And in terms of providing shade, that's really
useful for animals and also for people out walking as well,
isn't it?
ZOE HILL: Absolutely. You know, I saw a study this year where
they took the temperature of tarmac from an area that was
shaded by a tree versus not. And there was almost a 20 degree
difference. And that's kind of, it's a very simple way for us to
see the effect that just a simple tree cover can have, you
know, for us and wildlife.
AJAY TEGALA: That's absolutely incredible. And then also things
that are perhaps harder to see, just how much carbon they're
storing as well and how important it is for us to have
so many more trees.
ZOE HILL: You know, absolutely. You know, it's not just the
carbon they're able to store. You know, we're also talking
about kind of the reduced soil erosion, the flood mitigation
with the increased rainfalls we're seeing in winter. The
trees are able to help mitigate the floods we see with the
ability to take on water, slow the flow of water. Kind of those
kind of things.
AJAY TEGALA: So really trees are just nature's perfect way of
combating climate change and providing what the environment
needs.
ZOE HILL: They're so unique in what they're able to achieve,
but also so broad in what they can do.
AJAY TEGALA: And does climate change have any other big
bearings on your job?
ZOE HILL: Yeah, so there's lots of things that we see now,
especially like I've been in the role for three years. In the
three years, every single season has looked different. When I
look back to last year, trees weren't going dormant in the
nursery until almost December.
That really affects how we manage the nursery. I'm unable
to lift those trees until they've entered dormancy, which
means our rangers here on the ground have a much shorter
planting window.
And so that's kind of affected what I've grown this year. I'm
growing more cell-grown trees, which we can then go plant out
end of November, early November even, rather than our bare
rootstock. And I'm expecting to do that again this year. And
then kind of outside of the nest, we see those effects too,
you know.
Like last year, a lot of people would have worked out, you know,
you looked at an oak last year. It was an incredible mast year.
You know, there was no getting away from it for a lot of tree
species. And then what you're seeing this year is essentially
it's almost like a blank slate. There's nothing, you know.
A lot of these oaks put so much energy into trying to produce
seed last year, they've almost exhausted themselves. And what
we're going to see is more of that. We're going to see trees.
Not really doing a marsh year how they're supposed to. You
know, certain trees will do marsh years biannually.
Some trees do it every five, ten years. And what we're going to
see is they're going to become much more sporadic. You know,
we're not going to be able to predict when that's going to
come. Kind of going to happen.
AJAY TEGALA: So that makes it harder for the trees and harder
for you, I suppose, in managing your work.
ZOE HILL: Now that we're seeing trees seed earlier, what we're
seeing is by winter, a lot of our mammals and birds have a
depreciated food source. We're also going to see is our natural
regeneration of trees becoming much less, you know, a tree seed
needs certain conditions in order to germinate. And with
them seeding earlier.
We're not going to see those kind of conditions in the
environment they're being put into and so what we're going to
see is certain species struggling to get away
afterwards it's hard on the trees what we're seeing here you
know especially like this year if people looked out into their
garden they'll see a beech it's almost got no leaves on now
because they've just suffered so harshly in the drought and what
that also means for me is like this year a lot of our seed
ripened maybe four to six weeks earlier.
I plan my year out in kind of March, I look in my calendar,
I'm like, okay, I'll typically collect seed here, here, here.
And this year, I had to adjust completely, you know, I'd
usually start seed collecting now. I've been seed collecting
for the past six weeks, you know, I'm over halfway through
now. And so the climate change is having a massive effect on
even just the quality of fruit as well. You know, what we're
seeing is things like this year our hazelnuts, a lot of the
viable embryo inside it's not really there it's kind of just
the the drought has just made them suffer essentially.
AJAY TEGALA: When you're propagating you're putting a lot
of care into keeping them alive and helping them to establish
and water is essential for that obviously in the wild drought is
making it really hard how are you combating water shortage in
your role?
ZOE HILL: Water is a is a such a hard one in my role I can't
really put aside that water conservation, you know, these
trees I'm growing need water.
What I'm trying to do is I'm trying to water in the most
conservative way possible. Their rootstock is being watered by
kind of they're like seep hoses. They trickle out a little bit of
water twice a day, which allows the ground to stay moist.
But I'm not oversaturating. I'm not using more than I have to.
And then our kind of our pots are being watered twice a day,
but they're being watered at 6am and 7pm, which allows the least
amount of kind of surface evaporation.
And so whilst I'm still using the same amount of water, I'm
conserving it in a way because it's going to kind of last
longer on our trees.
AJAY TEGALA: Are there any species that are better at
growing in drier conditions that you're perhaps looking to
produce more of now?
ZOE HILL: Yeah, so there's a fair few, you know, we've got
things like our red oaks, they actually do well in kind of the
both extremes, they do okay when they're really wet and
waterlogged, but they also do okay when they're kind of more
droughted, you know, and we're seeing that in our environment
as well, you know, out there this year, while some of our
oaks have looked a little bit worse for wear, the red oaks
have looked very well, you know, they've seeded really well this
year, you know, in the nursery I'm seeing that too.
When you look towards our growing beds this year, the
greenest crops were those red oaks, so those aren't native to
the UK, but they can develop a really climate resilient
woodland in combination with our native trees.
Some people wouldn't have heard of provenance zones, but
essentially that's kind of regions of the UK that are kind
of specified by growers where Somerset is in a 305, we're
quite a southern provenance, we're kind of looking more
south. Sometimes that is just simply towards Cornwall.
Species down there that have been in the wild for a long time
things like our shrubs like our spindle and our older buckthorn
using those to foster our populations. When we're looking
at things like oaks we're looking to more places like
France where for they've been ahead of us in the climate we've
had for 20 30 years you know those trees have been able to
genetically adapt themselves to that and so we're looking more
towards Eastern Europe southern France regions to get our seed
from, to kind of it develop those more drought
characteristics in our seed and what we can do is we can plant
those in a mix in our woodlands and that can help develop a more
resilient long-term mix as they will kind of reproduce with our
local provenance seed and start kind of genetically hardening
almost.
AJAY TEGALA: Ah so you're gradually yeah you're gradually
sort of phasing them in alongside the native species
yeah.
ZOE HILL: Yes yeah.
AJAY TEGALA: And I suppose that that's important for the
wildlife that depends on them as well, being able to have shelter
when needed and also seeds for them to feed on too.
ZOE HILL: Absolutely. You know, that's, it's one of the really
important things with trees, you know, people often think of a
tree as just kind of as itself is just one of these amazing
habitats, but it's also, you know, the food it gives, it's
the shade it's giving, it's kind of the ground stability as well,
you know, on the edge of rivers and stuff. Trees almost lock in
the ground.
AJAY TEGALA: And so, yeah, you mentioned that obviously some of
the hazelnuts aren't so good at the moment. These red oaks are
doing well. Are there any other sort of particular native tree
species that you're worried about for the future in
particular?
ZOE HILL: When you look at trees now in the environment, it's
very obvious which ones are doing well, which ones aren't.
I'd be concerned for things like hornbeams, things like beeches.
You know, we're seeing increasingly these drier
conditions. They're just not thriving.
In our new woodland plantings they're the first things we're
seeing struggling and and I think you know I think they'll
be in our what in our kind of environment for a long time to
come but I do worry about the success we're going to have with
them in the future.
AJAY TEGALA: Because beech trees in particular they do a thing is
if I got this right called Marcescence is it well they're
supposed to hold on to those dead leaves until later on and
obviously that's not happening and So that's having an impact
on their life cycle?
ZOE HILL: Absolutely yeah and you know we're seeing in their
seed often as well like a lot of times now when I'm collecting
beach seed every year there's kind of been a reduction in
viable seed and obviously that'll then affect the onward
production of beach if we're not able to get viable seed the tree
also isn't self-seeding and so out in the wild we're probably
going to end up seeing less and less kind of natural
regeneration of things like beech and hornbeam.
AJAY TEGALA: They're two of my favourites actually. I remember
learning the Latin for beech is Fagus Sylvatica isn't it? Yeah.
I guess you're a bit of a whiz on all the Latin names as well.
ZOE HILL: Yeah. And so it's my volunteers. It's a love-hate
thing. I only do Latin.
It's universal. The Latin name is the Latin name. Let's go to a
garden plant, something like a geranium. That is a common name.
It's very different to the plant. It's a botanical name.
And that's kind of the same sometimes go for trees. You
know, if I said a goat willow. Someone might think of that as a
slightly different tree.
And so I tend to always try and use the Latin name. It enables
that we're all talking about the same thing, but sometimes a
Latin name can give the kind of details about the tree and where
you might find it. Like Acer Campestre is field maple. And so
it's of the woods, kind of that kind of thing. So you know
you're going to find it in a field.
AJAY TEGALA: I'm putting you on the spot a bit, but one of my
favourites is, I love to say, Fraxinus excelsior, which is
ash. Yes, yes. Do you know what that means? I've often wondered.
ZOE HILL: Do you know what? I don't.
AJAY TEGALA: No worries.
ZOE HILL: Because I just don't have much dealings with ash. And
so it's never been one that I've spent lots of time learning
about. But as a name, it just rolls off the tongue very well,
doesn't it?
AJAY TEGALA: Yeah. And it's interesting that you don't have
much that you're dealing with with ash. Because I was going to
ask about that, because obviously...
They've suffered a lot with the ash dieback disease and I've
heard that there might be some resilient strains coming through
but is that anything you're aware of or work with in any
way?
ZOE HILL: So I believe there is you know Kew have been out to
Holnicote in the past and they've collected seed from
trees that they believe to have some level resistance and.
Kind of within the nursery setting now we are allowed to
produce ash but from a disease point of view it's a very hard
line to draw if we if we grew ash in the nursery and it did
develop ash dieback there's not only a big kind of biosecurity
point there but it's also kind of a financial point you know
those trees grow in the nursery for two years if at the end of
that two-year cycle they get ash dieback that whole kind of
selection of trees has to unfortunately be destroyed and
so at the moment there's not the the desire for a lot of other
nurseries to grow ash yet but i think in the next 20 years we're
going to start seeing nurseries to producing those certain
strains of ash that are resistant you know we're seeing
in elms there's now disease resistant strains of elms that a
lot of bigger commercial nurseries are starting to
produce and so i slowly think over time we're going to see
these start to work their way back into our environment that
would be lovely because i i couldn't really even tell you
what an elm looks like because i see them so infrequently yeah
it's it's one of those that like As a kid, I remember seeing them
in hedgerows and things, but you never really correlated them
with anything because you didn't see them often enough.
And now, in the environment, they're so few and far between.
The ones you do see, you really hold a liking towards because
you know they're surviving and they're trying their hardest to
stop the beetle getting to them.
AJAY TEGALA: I work on a peatland reserve and obviously I
know that you'll be using peat-free soils. But I'm
intrigued to know a little bit about the kind of the growing
material, the soils and the mulches that you use.
ZOE HILL: Yes. So we are fully peat free.
I'm of the generation that's never been able to touch peat.
And so I've always had to kind of work with our peat free
compost. And a lot of the time, you know, when they come in, I
try and buy a compost that's kind of based on bark.
That tends to give the best base for growing media. And what
we'll do in the nursery is we'll kind of we'll tailor that to our
stock. A lot of the times now we're adding kind of moisture
retention media into those in order to them to essentially
stay moist the whole summer.
You know we're seeing a lot with our peat free media they will
dry out, they'll desiccate and almost become hydrophobic and so
those moisture retention medias allow this kind of compost to
stay. Moist for longer. You know, we'll add drainage to it,
we'll add some horticultural grit, you know, perlite, those
kind of things to allow the free movement of water in the
compost.
It doesn't stay water logged in wet conditions. You know, we'll
use in our bare root beds, it's a bit more kind of slightly
different to our kind of compost mix. We'll work with the soil,
we'll often mix in things like leaf mold, composted bark, we'll
occasionally use a green manure.
And so that will kind of grow on the growing bed when it's not in
use, work in. And not only does that kind of enrich the soil, it
also acts as almost like a bio-fumigant.
And so that's not a phrase a lot of people might have come
across. But it's essentially the green manure will kind of almost
suck out some of the nasties in the soil. It kind of allows the
soil to rest well and kind of over a couple of years.
The soil then becomes back to almost like a stable state and
it's kind of in its optimum for tree planting and so we use
green manures for that and so when we plant in it then we're
getting the best trees and what we're doing now more and more is
we'll mulch our trees saying that 20 years ago a lot of
gardeners wouldn't have done as they wouldn't have mulched their
beds as there wasn't a need whereas a lot of the time now
we'll mulch our beds because the moisture retention underneath
that mulch is 20 times what it would be without it.
AJAY TEGALA: And when you say mulching the beds, is that kind
of like leaf litter?
ZOE HILL: Yeah, so that can be leaf litter. It can be kind of
our garden compost. Sometimes we use small aggregate.
And that's for kind of some of the more kind of not delicate
seedlings, but some of the ones that kind of if there was a
living media, so things like your leaf mould or compost, if
they're on it, sometimes that can have a negative effect on
the soil.
And so we'll sometimes use like a small aggregate as a mulch
instead of those.
AJAY TEGALA: Gosh, there's so much to think about. Such a
complex, so many, so many factors. So is there one species
that grows particularly well, that you're particularly fond
of, perhaps a favourite, that is just a dream to work with?
ZOE HILL: Oh, see, I...
AJAY TEGALA: Or are they all hard?
ZOE HILL: I love...
As a gardener, I think a lot of people relate to this, is that
our favourite thing changes every time we see something
different. At the moment in the nursery, I'm loving Rowans.
They're...
Our bare root rows are growing so well in a season we're seeing
a metre and a half of growth you know they're still luscious
they're green. In one year I can get them from seed to plant was
ready to be planted out and in an earthly setting that's just
that's amazing that we're able to kind of captivate that much
growth in a tree to then plant out essentially.
AJAY TEGALA: We've talked about the process we've talked about
climate change I want to sort of look to the future because
obviously there's there's a lot of challenges, a lot of changes.
And I wondered what your thoughts are on what the UK
landscape from a tree perspective might look like in
50 years time.
ZOE HILL: Do you know what? I think we're going to see some
big changes in our landscape. You know, something I'd like to
see more of is kind of that kind of softer woodland edges. You
know, I want a bit more of that mosaic of habitats. I want our
kind of our woodlands and our heathlands to mix up a bit more.
You know, that's how we're going to develop a more resilient
woodland. It would be amazing if. We stopped having a bit more
of that kind of monoculture. Often in plantings, we used to
see people like, we want an oak woodland, we want a beech
woodland.
It'd be great to see those being mixed with kind of those native
broadleaf shrubs as well. You know, the underlay of food for
dormice, the birds, kind of a bit more maybe restored
temperate rainforest around here. You know, there's a lot of
those in the south end of the country. And we're very lucky
that we're able to have that habitat.
I'd love to see some more of that.
AJAY TEGALA: And for your role specifically, I mean, the
practical realities of growing tens of thousands of trees into
the future. How do you see that changing?
ZOE HILL: I think it's a hard one. I think nurseries always
over time have been very dynamic. We're very kind of we
become very aware of the changes because in that space every year
things change. And I think what we're going to see is we'll
grow.
I think it's how we're growing things. I think we're going to
revert back to growing things bare root.
40 years ago, bare root was the way we grew trees. That was the
best way. And then over time, we started growing sail-grown trees
just because they're more efficient. Whereas I think for a
quality of tree, we're going to go back towards bare root. And I
see that in the nursery as well.
We'll start growing back more towards bare root. I think how
we kind of manage water in the nursery will change. I think
there's going to be a lot more mulching, a lot more wider plant
spacings to allow that water to be absorbed by the tree better.
AJAY TEGALA: And just to pick up on bare root, I mean, I'm
visualising kind of like no soil and just roots. Is that what it
is?
ZOE HILL: That's pretty much it. Yeah. You know, we'll plant our
tree in the ground. It'll grow on for a season. We'll then lift
it. And it might have some soil attached to the roots, but
typically it'll be kind of.
A non-root bound structure essentially so we'll lift it and
it'll be they're typically larger which is why we kind of
went away from them you know the smaller cell growing trees were
just a lot easier for rangers and people to plant so yeah.
AJAY TEGALA: And in terms of water and water availability one
thing I'd really like to see is more use of the kind of the the
bath water and the dish water and this summer I was spreading
that in the garden and there's so much water that's wasted that
could be used to help things grow.
ZOE HILL: Absolutely. At home, every time I do the washing up,
I'll save that grey water to then use in the garden. You
know, personally, I'll use kind of natural soaps, whether it's
in kind of my bath showers, whether it's in my washing up.
And so I'm sure the water I'm putting out isn't full of
chemicals. I'm also thinking like the things that I'm washing
up in, we don't want to be putting oils and things really
into our gardens.
And so I think it is also just knowing what your what you're
putting out into your garden and there's a lot more so just
rainwater conservation a lot of people now just at home they're
going to start putting water butts on their sheds. You know
I'm in Somerset and for the first time in 50 years we've got
a hose pipe ban that's something we've never dealt with here and
so I think even just locally people are going to start
thinking more about water conservation whether that's
rainwater grey water and I think we will start seeing that in the
nursery sector but We're talking commercial quantities and so
it's going to be how we're managing our water I think.
AJAY TEGALA: And so for ordinary gardeners obviously they can use
grey water that's one tip for them but do you have any other
tips for people at home and how they can help their trees have
the best chance for the future?
ZOE HILL: I'm going to say mulching is really important. I
think regular little and often waters are better than once a
week going out and giving a large water. There's quite
interesting things now. They're like water bags that go around a
tree or near a tree, and you can fill those up.
And instead of kind of you water the ground, and in the state
that it's in, it runs off, those little water bags will allow the
water to slowly trickle into the soil. And so I'd recommend
those. And I think just those few little things will help
trees establish better.
AJAY TEGALA: And once they've established, they can go on to
live for so many years. And do you ever think...
ZOE HILL: They can outlive us.
AJAY TEGALA: Yeah, I was going to say, yeah. Do you ever think
about some of your trees and the legacy they're going to have
beyond your lifetime?
ZOE HILL: Absolutely.
Some of the rangers here took me to a planting that was done the
year I was born. And when you look at it, you can't even
fathom that it's only that old when you look at it. The trees
that we've already grown in the nursery that have been planted
out, I think of those in 20 years time.
I think that's going to be an established woodland just in 20
years. I can't imagine to even think of it in 100, 200, 300
years. We're talking future generations down the line. And
so it's almost unfathomable to think about.
AJAY TEGALA: And to conclude, do you think you'd have a message
for those future generations in years to come in relation to
your experience and to trees?
ZOE HILL: I think it's all just about appreciating what we've
got. I think it's just appreciate what's around you,
you know, look after the small bits we have, as well as
nurturing those we're going to create and just kind of adapt.
The world we have is changing. We're going to have to change
what we're doing. And so just be welcoming of kind of change.
AJAY TEGALA: I think that's a really great message. And I've
thoroughly enjoyed listening to sort of a taste of your life and
the amazing things you're doing. So many things to think about.
And yeah, I'm kind of envious, really. I'd love to come and see
you and join you one day.
ZOE HILL: Oh, that'd be fabulous.
