Looking after the River Esk and its wildlife - Katrina Vernon

Katrina Vernon, a volunteer with Buglife, talks with host Osbert Lancaster.

Listen to hear how Kat’s work taking children out in nature led to her becoming a citizen scientist monitoring the health of the River Esk, and later training others to do the same.

Kat reflects on how even when things can seem bad, coming together to work with other people to take action makes a difference. Kat talks about the importance not just of spending time in nature, but also learning about what’s going on in our rivers and woodlands and how we can care for them.

Changing Climate, Changing Midlothian explores what the climate and nature emergency means with people living and working in the county. Their reflections will help inform discussions as cross sector representatives and community leaders meet in October to agree a new Single Midlothian Plan setting collective outcomes and actions for the next three years.

Changing Climate, Changing Midlothian is produced for the Midlothian Community Planning Climate Emergency Group by Thrivable Scotland, and is kindly supported by Midlothian Climate Action Hub, Midlothian Community Planning and Midlothian Energy Ltd.

Transcript
Kat Vernon:

My son was a zoologist and when he went to uni, they

2

:

said to him pick three species,

which are in the endangered list.

3

:

And by the time he was

finished, they were extinct.

4

:

so it can be quite, quite drastic.

5

:

. you've got to do what you can

and not overly think 'cause then

6

:

you would become beside yourself

7

:

I'm Osbert Lancaster, and this is

changing Climate, Changing Midlothian,

8

:

where we explore what the climate and

nature emergency means with people

9

:

living and working in the county.

10

:

In this episode, I'm talking with

Katrina Vernon, a volunteer with Bug

11

:

Life as we walk in Meadowfield Park

on the side of Arthur's Seat, looking

12

:

out over Midlothian in the distance.

13

:

I started by asking Kat how she

came to be a volunteer with Bug

14

:

Life and the Riverfly Project.

15

:

Kat Vernon: I was working out in

Midlothian at Newbattle Abbey and, uh,

16

:

was out with a group of children doing

the forest kindergarten, and we came

17

:

across Rebecca Lewis, and Clive at the

riverside, doing some water sampling Uhhuh

18

:

and we went over and asked her what she

was doing and she showed the children

19

:

and everything what she was up to.

20

:

And, um, then she came and did a,

a sort of group session with them

21

:

when it kinda led to adding it to

our green flag and things like that.

22

:

So it covered the whole of

the curriculum for excellence,

23

:

when we were doing it as well.

24

:

So, and then just got

really interested in it.

25

:

So Becky asked me if , I'd

like to do the training.

26

:

Mm-hmm.

27

:

So I ended up doing the training

and one of the sites was short of a

28

:

few people, so down at Roslin Glen

29

:

. So I go down there with my friend Amy,

and we do it once a month and collect

30

:

mm-hmm a sample, which then gets

31

:

Osbert: so out with the

little, dip nets, they call

32

:

' Kat Vernon: waders on and kick sampling.

33

:

And then dividing the species, so it

can take up to two to three hours,

34

:

but I always think it's just like

once a month and you're doing a bit

35

:

for the environment and everything,

36

:

I, I became really interested in it.

37

:

So I'm not only trained in it Yeah.

38

:

I'm now training so that I can actually

train people in it, so that they can

39

:

go out and we can create more sites

and create more data, create more

40

:

connections with SEPA things are happening

which is all always a good thing.

41

:

Osbert: Why does it matter?

42

:

Why do we need to do it every month?

43

:

What's it telling us?

44

:

Kat Vernon: Uh, it matters because,

you know, we have these indicators,

45

:

the species that we collect

they're all part of the food chain.

46

:

So for example, if we didn't have

them cleaning up all the debris

47

:

and everything on the river, then

our rivers will get mucky as well.

48

:

But on top of that, they feed the fish.

49

:

And it was actually the anglers

that started this up originally

50

:

because they noticed that there

wasn't as many fish, there wasn't

51

:

as many insects and they started

this to start monitoring the river.

52

:

we also were involved in a project where

we all came together and we went up

53

:

to Gladhouse, the source of the river

and insects are, I would say they're

54

:

about four to five times the size in

comparison to further down the river.

55

:

So,

56

:

Osbert: so if that they've got better

food sources or less pollution or

57

:

Kat Vernon: Yeah.

58

:

Less pollution.

59

:

Less pollution.

60

:

Yeah.

61

:

Better food sources.

62

:

Just the whole thing.

63

:

Cleaner water,

64

:

yeah.

65

:

The funding that we've done just now

looks at the species not just the

66

:

family , breaking them down even further.

67

:

Osbert: Yeah.

68

:

Kat Vernon: And they're all susceptible

to different types of pollution.

69

:

So it should come out with more

data , the south and the north and see

70

:

what's happening across both sites,

you know, of the Esk River itself.

71

:

Osbert: That a beautiful

blue butterfly there.

72

:

Kat Vernon: That would be the small blue,

73

:

Osbert: Another one there.

74

:

Yeah.

75

:

It's like little jewels.

76

:

Kat Vernon: You know, I grew

up in nature , I loved it but I

77

:

didn't know that much about it.

78

:

Mm-hmm.

79

:

And then did my forest school

training just taught me so much

80

:

about plants and trees and birds

and butterflies So I learned a lot

81

:

doing that and then going out into

nature with the children, how great

82

:

it was for their health and wellbeing.

83

:

, then when we met Becky as well, I knew

there was insects on, on the river.

84

:

Yeah.

85

:

You know, you see 'em flying.

86

:

But I didn't clock.

87

:

There was insects in the

river as well, you know.

88

:

Osbert: Yeah.

89

:

Unless you look for then

you wouldn't, you wouldn't.

90

:

Kat Vernon: Yeah.

91

:

Osbert: Yeah.

92

:

Kat Vernon: So you can

be in nature but not

93

:

Osbert: Yeah.

94

:

Kat Vernon: Not know about it,

you know, it's, uh, and I think

95

:

that's a life learning journey

96

:

Osbert: as

97

:

Kat Vernon: well.

98

:

Uhhuh, you know, you get

interested in something.

99

:

Yeah.

100

:

Like just now it's like the bird sounds

101

:

Osbert: Yeah.

102

:

Kat Vernon: You know, that

I'm trying to identify.

103

:

And

104

:

Osbert: how are you going with that?

105

:

I find like, I keep on like hear

a bird, I put out the Merlin app.

106

:

I go always a such and such

107

:

Kat Vernon: uhhuh.

108

:

Osbert: I hear the same sound

again the next day, but I've

109

:

forgotten entirely what it is.

110

:

Kat Vernon: I know I pick up

a few, like that's the magpie

111

:

so many people interested in birds, but

there's so few interested in insects.

112

:

Mm-hmm.

113

:

And especially insects in the river.

114

:

There was a group down at Auchendinny,

down at the Threee Hares there,

115

:

they'd asked us to come and sample

the water, they were a bit concerned.

116

:

So, we went down, we did the

river dip, showed them all, insect

117

:

got 'em to separate them all.

118

:

And you know, from that I'm hopefully

gonna be training a couple of

119

:

people that were interested in that

mm-hmm that have came back Yep.

120

:

That are now going then go in and

start doing their own sampling as well.

121

:

Mm-hmm.

122

:

So, so in that respect then you're

passing the word on and Yeah.

123

:

Hopefully will grow, like

124

:

Osbert: Like sort of ripples in a pond.

125

:

Kat Vernon: Yeah.

126

:

and even when we're, we're doing our

samples at the side, at Roslin, the

127

:

people that walk past us with the dogs

or children and they'll come, come

128

:

over and ask us what we're doing mm-hmm,

and show them all the invertebrates in

129

:

in the dish they're very interested in

it as well, and there's a lot of them

130

:

are curious if the water's clean or

whether it's been dirty or whether you

131

:

know, or what, what would affect it.

132

:

Osbert: You mentioned how good being out

in nature is for the health and wellbeing

133

:

of the kids, but what does that actually

like, look like in practise rather than

134

:

just ticking a health and wellbeing box.

135

:

Kat Vernon: Well, I always

think about my youth.

136

:

I was out and about and I was

only home when it was dinner

137

:

time you're out playing all day.

138

:

. So you're out in fresh air, you're

running about, you're active,

139

:

you eat better, you sleep better.

140

:

It's just the whole thing.

141

:

And because you take out small groups,

you've got that nurture mm-hmm.

142

:

And that care.

143

:

Mm-hmm.

144

:

And the kind of bond that you

create with the group as well.

145

:

Mm-hmm.

146

:

Osbert: So that you've got that

health and wellbeing aspect.

147

:

Mm-hmm.

148

:

And on top of that the curriculum stuff.

149

:

Kat Vernon: Yes.

150

:

Osbert: Yeah.

151

:

Is that happening at all

stages through the school?

152

:

The, that sort of potential

for that to come together?

153

:

Or is that

154

:

Kat Vernon: It depends, it's like

your environmental stewards, some

155

:

schools will have them, some schools

might not have them as active as others.

156

:

This was early years I

was working in as well.

157

:

Osbert: Right.

158

:

And early years, what does that

159

:

Kat Vernon: cover?

160

:

That's, that covers like

three to five year olds.

161

:

But today I was out with groups that

were up to about 12 or 13 year olds.

162

:

There are, there are groups for different

ages going up and different needs as well.

163

:

And it has came on a lot compared

to when it first started up.

164

:

Osbert: How have you seen that growth

when it started it a bit, bit different, a

165

:

bit new, a bit unusual is it happening in

166

:

most schools, most nurseries these days?

167

:

Kat Vernon: There's a group

called MOWL, which is Midlothian

168

:

Outdoor Woodland Learning Group,

uhhuh, which I'm part of as well.

169

:

Yeah..

170

:

And, they come together each month and

they do training, for example, I was

171

:

doing training with them the other week

there where we were making nettle

172

:

cakes and make the cordage uhhuh.

173

:

And it's teaching them to

take new skills back Uhhuh.

174

:

And they have a wider group as well,

which is OWL Scotland they come together

175

:

a couple of times a year, in places

like Benmore and stuff like that.

176

:

I suppose it's like climate change

and that's here and we basically

177

:

need, maybe need's not the word,

but it would be beneficial if the

178

:

children knew and got to love nature.

179

:

And then they would become the stewards

going forward so if they're outdoor

180

:

players, I mean even for the wellbeing

of people as well, you know, like

181

:

children being outdoors and active

182

:

And I mean, like I said, you can

be in nature and not know about it.

183

:

Osbert: Yes.

184

:

Kat Vernon: You know, if you're not

doing those sciences then would,

185

:

you know there were insects in the

river, would you know that there's

186

:

food in the trees and the plants?

187

:

Osbert: You talked about spending lots

of time outside when you're growing

188

:

up and like now with the wildfires

and climate change, seas becoming

189

:

warmer and, and all the rest of it.

190

:

How does that leave you

feeling about all of that?

191

:

Kat Vernon: My son was a zoologist

and when he went to uni, they

192

:

said to him pick three species,

which are in the endangered list.

193

:

And by the time he was

finished, they were extinct.

194

:

Osbert: Whoa.

195

:

Kat Vernon: Um, so it can

be quite, quite drastic.

196

:

. So I think, I think you've got

to do what you can and not overly

197

:

think 'cause then you would become

beside yourself if you like.

198

:

Yeah.

199

:

. Something that you can

do to make a difference.

200

:

And whether it's just, like I said,

once a month you go and do a river

201

:

sample that collects the data that maybe

support the change that's required.

202

:

And I think even like Becca's doing,

she's showing people what she's doing and

203

:

making them aware, is really as important,

because if you're not aware of what's

204

:

happening even on your doorstep, you know

205

:

I think everybody really wants to help and

they know about climate change and they

206

:

want to help, but whether they have time.

207

:

It can be quite difficult, but I think,

I think little things are important

208

:

as, and doing as much as you can.

209

:

We come together as a Riverfly Group

to do species identification and stuff

210

:

like that do training and it is a

lovely group of people, it's a nice

211

:

group to be with and you look forward

to your once some month conversation.

212

:

And, and having the sites throughout

Midlothian right down to, to

213

:

Musselburgh is amazing, you know?

214

:

the amount of people

that are involved in it.

215

:

Osbert: But anyone can do this.

216

:

It's not about having a degree first

and say before you can do this,

217

:

Kat Vernon: get stuck in, even

when Rebecca says you're gonna do

218

:

this podcast, I says, I can't say

that the insects names properly.

219

:

We've got different names for them.

220

:

We call them Flat Bodies

and Speedy Darters and

221

:

. Osbert: And what would you say to someone

who was thinking, I see what's going

222

:

on, I'm, you know, concerned about it,

I want to be doing something useful.

223

:

You know, what, what would

your advice be to them?

224

:

Kat Vernon: I would say definitely

just try and get involved in a group

225

:

that you, you're interested in.

226

:

You know, something that's, you

can make that small change with.

227

:

Some of the sites, we've got lots

of people that are come together.

228

:

So if you're not there one month, it

doesn't really matter, you're doing

229

:

what you can do when you can do it.

230

:

You're out in nature, you're being

with friends and you're sharing the

231

:

experience whether it's good or bad.

232

:

So, but I think just getting

involved in something that makes

233

:

a difference is really important.

234

:

Osbert: Looking ahead, all the different

partners public sector, the third

235

:

sector, you know, private sector groups

involved in those, those discussions

236

:

coming up with that plan is there

something you would really like them

237

:

to be thinking about as they're working

on that and something you think should

238

:

be different than it is at the moment.

239

:

What would, what would

that be do you think?

240

:

Kat Vernon: Well, it'd be clean rivers

to the end it with the great big insects

241

:

and it to feed the fish that are gonna

feed the birds and looking to, educate

242

:

people in what is happening on the

rivers and improving them as well.

243

:

Just to have the improvement going

forward, the data being used in a

244

:

positive way that'll bring that change,

that improves the river systems and our

245

:

land and our water they're all important.

246

:

Nature's important.

247

:

Osbert: And there you have it.

248

:

You've been listening to Kat

Vernon, who volunteers with Buglife

249

:

on Changing Climate, Changing

Midlothian with me, Osbert Lancaster.

250

:

I hope you found the conversation

as fascinating as I did.

About the Podcast

Changing Climate, Changing Midlothian
Reflections from our community
What does the climate and nature emergency mean for people living and working in Midlothian?

I talk with people across the county and ask what would help them and others make more positive changes for the communities and places they care about.

We’ll discuss how organisations could work together better to co-create, deliver and support even more action on the ground.

As well as sharing inspiring stories and insights with you and other listeners, the conversations in this podcast will help cross sector representatives and community leaders as they meet in October to set collective outcomes and actions for the next three years in the Single Midlothian Plan.
