1
00:00:00,000 --> 00:00:02,865
Jacob Swanson and I
will be presenting

2
00:00:02,865 --> 00:00:04,800
together where
both since at

3
00:00:04,800 --> 00:00:06,615
PCC Portland
Community College,

4
00:00:06,615 --> 00:00:08,160
studying environmental
science as

5
00:00:08,160 --> 00:00:10,245
the introducer mentioned,

6
00:00:10,245 --> 00:00:11,790
a professor
advanced burnish

7
00:00:11,790 --> 00:00:13,380
joined us as a coauthor.

8
00:00:13,380 --> 00:00:16,710
This is quantifying
ecosystem services using

9
00:00:16,710 --> 00:00:18,630
AI tree model with an

10
00:00:18,630 --> 00:00:20,070
herbivorous provides

11
00:00:20,070 --> 00:00:22,420
educational opportunities
for students.

12
00:00:22,420 --> 00:00:24,540
Next slide, please.

13
00:00:26,110 --> 00:00:30,050
In 2021 fall term students

14
00:00:30,050 --> 00:00:32,420
in the applied environmental
studies course

15
00:00:32,420 --> 00:00:34,670
conducted research
to quantify

16
00:00:34,670 --> 00:00:36,740
the ecosystem
services provided by

17
00:00:36,740 --> 00:00:39,050
the Urban for us
within the PCC,

18
00:00:39,050 --> 00:00:41,495
Rock Creek Environmental
Studies Center.

19
00:00:41,495 --> 00:00:42,980
This is done using

20
00:00:42,980 --> 00:00:44,960
actually if a
model is commonly

21
00:00:44,960 --> 00:00:46,790
used for Australia
analysis tool

22
00:00:46,790 --> 00:00:49,145
created by the US
Forest Service.

23
00:00:49,145 --> 00:00:50,990
This fulfilled
community-based

24
00:00:50,990 --> 00:00:52,039
learning objectives

25
00:00:52,039 --> 00:00:53,720
and obtain data
to be used by

26
00:00:53,720 --> 00:00:56,600
PCC Sustainability Team
within their work for

27
00:00:56,600 --> 00:00:59,435
the 2021 climate
action plan

28
00:00:59,435 --> 00:01:02,135
as well as the Tree
Campus USA program.

29
00:01:02,135 --> 00:01:04,230
Next slide, please.

30
00:01:04,980 --> 00:01:07,900
I'll click Environmental
Studies Center is

31
00:01:07,900 --> 00:01:11,800
a 110 acre natural
area at the edge of

32
00:01:11,800 --> 00:01:14,230
the urban growth
boundary that serves as

33
00:01:14,230 --> 00:01:15,909
a living laboratory
facilitating

34
00:01:15,909 --> 00:01:18,265
experiential learning
opportunities.

35
00:01:18,265 --> 00:01:20,470
It's mosaic of
diverse habitats,

36
00:01:20,470 --> 00:01:23,365
wetland oak woodland
and coniferous forests.

37
00:01:23,365 --> 00:01:25,660
But kick serves as
a wildlife corridor

38
00:01:25,660 --> 00:01:27,835
and in order to
inverter at the site.

39
00:01:27,835 --> 00:01:31,465
In 2017, clean water
services, again,

40
00:01:31,465 --> 00:01:33,355
the Rock Creek floodplain

41
00:01:33,355 --> 00:01:35,185
enhancement project
on the site.

42
00:01:35,185 --> 00:01:36,520
But the goals
of increasing

43
00:01:36,520 --> 00:01:37,689
floodplain connectivity,

44
00:01:37,689 --> 00:01:39,355
slowing and storing
more water,

45
00:01:39,355 --> 00:01:42,205
improving water quality
and wildlife habitat.

46
00:01:42,205 --> 00:01:43,900
The photo on
the left shows

47
00:01:43,900 --> 00:01:45,070
some of the land
clearing that

48
00:01:45,070 --> 00:01:46,360
has occurred just beyond

49
00:01:46,360 --> 00:01:48,195
the Rock Creek
Environmental city center,

50
00:01:48,195 --> 00:01:49,955
the urban growth boundary.

51
00:01:49,955 --> 00:01:51,845
The square root of
the aerial image

52
00:01:51,845 --> 00:01:53,750
shows a portion of
land that was cleared

53
00:01:53,750 --> 00:01:55,700
in the summer of 2021 to

54
00:01:55,700 --> 00:01:56,750
build more housing for

55
00:01:56,750 --> 00:01:57,815
the growing population.

56
00:01:57,815 --> 00:01:58,760
And there are already

57
00:01:58,760 --> 00:02:00,169
more housing developments

58
00:02:00,169 --> 00:02:03,245
in this area that are
shown on the URL image.

59
00:02:03,245 --> 00:02:05,090
During the land
clearing last summer,

60
00:02:05,090 --> 00:02:06,635
much of the
riparian buffer

61
00:02:06,635 --> 00:02:08,420
protecting the
wetland on Canvas,

62
00:02:08,420 --> 00:02:10,220
once removed as land was

63
00:02:10,220 --> 00:02:13,205
cleared right to the
edge of PCCs property.

64
00:02:13,205 --> 00:02:15,050
We recently
learned tower at

65
00:02:15,050 --> 00:02:16,580
that clean water
service now

66
00:02:16,580 --> 00:02:17,735
plants to replant

67
00:02:17,735 --> 00:02:20,330
a vegetative buffer
on PCCs property.

68
00:02:20,330 --> 00:02:22,590
Next slide, please.

69
00:02:22,780 --> 00:02:26,390
Oh, and we focus
specifically on the forest

70
00:02:26,390 --> 00:02:27,680
has been Rock Creek
Environmental

71
00:02:27,680 --> 00:02:29,255
Studies Center
for our study,

72
00:02:29,255 --> 00:02:32,180
we conducted stratified
random sampling.

73
00:02:32,180 --> 00:02:34,430
You can see our city
area on the right.

74
00:02:34,430 --> 00:02:36,515
There are 54 a strata

75
00:02:36,515 --> 00:02:39,065
that represent five
different communities,

76
00:02:39,065 --> 00:02:41,615
including upland
coniferous forest,

77
00:02:41,615 --> 00:02:43,805
oak woodland,
bottleneck forests.

78
00:02:43,805 --> 00:02:45,605
And total there were 33

79
00:02:45,605 --> 00:02:48,035
for us it acres in
our study area,

80
00:02:48,035 --> 00:02:50,509
we sampled 22 circular

81
00:02:50,509 --> 00:02:53,450
400 meter squared plots.

82
00:02:53,450 --> 00:02:54,920
And you can see
some of our

83
00:02:54,920 --> 00:02:57,020
classmates
gathering data and

84
00:02:57,020 --> 00:02:59,300
we measured all choose
at the diameter or

85
00:02:59,300 --> 00:03:01,340
greater than two
inches in each plot.

86
00:03:01,340 --> 00:03:03,649
Identify their
species code, DPH,

87
00:03:03,649 --> 00:03:06,200
an estimated the
percent canopy dieback.

88
00:03:06,200 --> 00:03:09,770
And total 651 trees
were measured.

89
00:03:09,770 --> 00:03:11,180
This data as an input

90
00:03:11,180 --> 00:03:12,745
and they actually
go model,

91
00:03:12,745 --> 00:03:15,260
extrapolate our
data to estimate

92
00:03:15,260 --> 00:03:17,630
the ecosystem
services provided

93
00:03:17,630 --> 00:03:19,175
by our total study area.

94
00:03:19,175 --> 00:03:22,130
I'll hand this
off to take it.

95
00:03:22,130 --> 00:03:24,320
Great. Thank you, Amy.

96
00:03:24,320 --> 00:03:26,480
Hi, my name is
Jacob Swanson.

97
00:03:26,480 --> 00:03:28,295
I'll be going
over our results.

98
00:03:28,295 --> 00:03:30,110
So this graph shows
the estimated

99
00:03:30,110 --> 00:03:31,880
gross carbon
sequestration in

100
00:03:31,880 --> 00:03:33,710
metric tons per year for

101
00:03:33,710 --> 00:03:34,820
the species with
the greatest

102
00:03:34,820 --> 00:03:36,305
carbon sequestration.

103
00:03:36,305 --> 00:03:37,730
The estimated sample size

104
00:03:37,730 --> 00:03:39,455
given by the IQ
EQ or model,

105
00:03:39,455 --> 00:03:41,960
was 10 thousand
to 120 trees.

106
00:03:41,960 --> 00:03:43,580
We see here that
the species with

107
00:03:43,580 --> 00:03:45,680
the greatest carbon
sequestration

108
00:03:45,680 --> 00:03:46,970
is big leaf maple and

109
00:03:46,970 --> 00:03:49,370
Douglas for these two
species account for

110
00:03:49,370 --> 00:03:50,810
roughly 64 percent of

111
00:03:50,810 --> 00:03:52,310
the carbon
sequestration that is

112
00:03:52,310 --> 00:03:54,575
taking place within
this urban forests.

113
00:03:54,575 --> 00:03:56,780
The total gross
carbon sequestration

114
00:03:56,780 --> 00:03:58,100
for this study area is

115
00:03:58,100 --> 00:03:59,480
estimated to be just over

116
00:03:59,480 --> 00:04:02,400
48 metric tons per year.

117
00:04:02,770 --> 00:04:05,120
This graph shows the total

118
00:04:05,120 --> 00:04:06,500
estimated carbon
storage in

119
00:04:06,500 --> 00:04:08,120
metric tons for
the species with

120
00:04:08,120 --> 00:04:10,310
the greatest amount
of carbon storage.

121
00:04:10,310 --> 00:04:11,930
The total carbon
storage for

122
00:04:11,930 --> 00:04:13,550
our study area is
estimated to be

123
00:04:13,550 --> 00:04:17,525
just over 1963 metric tons

124
00:04:17,525 --> 00:04:19,085
of the species sampled,

125
00:04:19,085 --> 00:04:20,780
Douglas first stores
the most carbon

126
00:04:20,780 --> 00:04:21,830
within the forest at

127
00:04:21,830 --> 00:04:23,915
approximately 49.1%

128
00:04:23,915 --> 00:04:25,460
of the total
carbon stored.

129
00:04:25,460 --> 00:04:26,780
What I like
about this graph

130
00:04:26,780 --> 00:04:27,815
in the previous graph,

131
00:04:27,815 --> 00:04:29,180
as you can get a
generalized idea of

132
00:04:29,180 --> 00:04:30,230
the forest structure in

133
00:04:30,230 --> 00:04:32,045
the biodiversity
of the forest.

134
00:04:32,045 --> 00:04:33,665
We have Douglas
fir and degli

135
00:04:33,665 --> 00:04:35,180
NAPL that Domini areas of

136
00:04:35,180 --> 00:04:37,040
the forest canopy and

137
00:04:37,040 --> 00:04:39,125
sequestering the greatest
amount of carbon.

138
00:04:39,125 --> 00:04:40,580
And we can also
get an idea of

139
00:04:40,580 --> 00:04:42,320
the species living
in the understory or

140
00:04:42,320 --> 00:04:43,490
species that are
less commonly

141
00:04:43,490 --> 00:04:44,750
distributed throughout

142
00:04:44,750 --> 00:04:46,580
the landscape and
therefore store

143
00:04:46,580 --> 00:04:49,410
and sequester less carbon.

144
00:04:49,690 --> 00:04:51,980
Now that we have
some estimates

145
00:04:51,980 --> 00:04:53,045
in mind that said,

146
00:04:53,045 --> 00:04:55,055
put it all into
perspective.

147
00:04:55,055 --> 00:04:56,840
The carbon
sequestration for

148
00:04:56,840 --> 00:04:58,400
the Rock Creek Environmental
Studies Center

149
00:04:58,400 --> 00:04:58,670
for

150
00:04:58,670 --> 00:04:59,840
us is estimated to be

151
00:04:59,840 --> 00:05:02,555
just over 48 metric
tons per year.

152
00:05:02,555 --> 00:05:04,070
This amount is relative to

153
00:05:04,070 --> 00:05:05,450
the annual carbon
footprints have

154
00:05:05,450 --> 00:05:08,450
a typical US households
are our campus,

155
00:05:08,450 --> 00:05:09,830
PCC, rock creek 29.

156
00:05:09,830 --> 00:05:12,110
Carbon dioxide equivalence
was estimated to

157
00:05:12,110 --> 00:05:15,935
be 10,259 metric tons.

158
00:05:15,935 --> 00:05:18,500
It is estimated to
be equivalent to

159
00:05:18,500 --> 00:05:19,880
the greenhouse
gas emissions

160
00:05:19,880 --> 00:05:21,110
offset by a forest,

161
00:05:21,110 --> 00:05:22,640
the size of B, opal creek

162
00:05:22,640 --> 00:05:25,070
wilderness prior
to the 2020 fires.

163
00:05:25,070 --> 00:05:26,540
Half of the people in his

164
00:05:26,540 --> 00:05:28,190
prior to 2020 fires.

165
00:05:28,190 --> 00:05:29,915
To give a visual
perspective,

166
00:05:29,915 --> 00:05:31,130
we have included
a picture of

167
00:05:31,130 --> 00:05:34,265
the PCC campus and the
opal creek wilderness.

168
00:05:34,265 --> 00:05:36,260
So it's estimated
that about half of

169
00:05:36,260 --> 00:05:37,400
this size forest will

170
00:05:37,400 --> 00:05:38,930
offset the carbon
emissions.

171
00:05:38,930 --> 00:05:40,535
Have an institution
the size of

172
00:05:40,535 --> 00:05:42,575
PCC Rock Creek annually.

173
00:05:42,575 --> 00:05:43,610
Now I'm going to pass

174
00:05:43,610 --> 00:05:44,690
things back to Amy where

175
00:05:44,690 --> 00:05:45,620
she will share some of

176
00:05:45,620 --> 00:05:47,315
the student
research projects.

177
00:05:47,315 --> 00:05:48,515
Thank you.

178
00:05:48,515 --> 00:05:49,880
Hi professor at carefully

179
00:05:49,880 --> 00:05:51,050
the scientists project.

180
00:05:51,050 --> 00:05:53,435
So that seems to be
empowered to communicate

181
00:05:53,435 --> 00:05:55,250
our results to a
target audience

182
00:05:55,250 --> 00:05:57,020
in the form of a
published study.

183
00:05:57,020 --> 00:05:57,545
Mouth.

184
00:05:57,545 --> 00:05:58,280
Shut.

185
00:05:58,280 --> 00:06:00,634
These with the students
intended audience.

186
00:06:00,634 --> 00:06:02,165
This sustainability
team and

187
00:06:02,165 --> 00:06:03,680
others had been PCC.

188
00:06:03,680 --> 00:06:05,540
And here are
the Story Maps.

189
00:06:05,540 --> 00:06:07,265
The project on the
left, targeted

190
00:06:07,265 --> 00:06:08,990
PCCs board of directors

191
00:06:08,990 --> 00:06:10,760
discussing the
results of our study,

192
00:06:10,760 --> 00:06:12,710
the importance of the
bio-diverse for us,

193
00:06:12,710 --> 00:06:15,005
for carbon storage
and sequestration.

194
00:06:15,005 --> 00:06:16,265
And argued that the rocket

195
00:06:16,265 --> 00:06:17,660
Environmental
Studies Center

196
00:06:17,660 --> 00:06:20,150
is worthy of preserving
and funding.

197
00:06:20,150 --> 00:06:21,740
The project on
the upper-right

198
00:06:21,740 --> 00:06:23,090
targeted a wider audience,

199
00:06:23,090 --> 00:06:24,440
including local residents

200
00:06:24,440 --> 00:06:25,640
and decision-makers.

201
00:06:25,640 --> 00:06:27,320
This group
discussed ecosystem

202
00:06:27,320 --> 00:06:28,610
services omitted and the

203
00:06:28,610 --> 00:06:30,290
methodology
including Rock Creek

204
00:06:30,290 --> 00:06:32,030
serving as a
wildlife corridor,

205
00:06:32,030 --> 00:06:33,425
suggested creating

206
00:06:33,425 --> 00:06:35,840
wildlife passage under
aborted roadway,

207
00:06:35,840 --> 00:06:38,030
highlighted community
concerns about

208
00:06:38,030 --> 00:06:39,410
mature tree removal in

209
00:06:39,410 --> 00:06:40,895
Washington County
and suggested

210
00:06:40,895 --> 00:06:42,380
update updates to

211
00:06:42,380 --> 00:06:44,210
the Washington
County tree code.

212
00:06:44,210 --> 00:06:45,260
The group that created

213
00:06:45,260 --> 00:06:46,610
the bottom-right project

214
00:06:46,610 --> 00:06:48,500
targeted local
policymakers.

215
00:06:48,500 --> 00:06:50,060
And you see I
cheat, you go model

216
00:06:50,060 --> 00:06:51,620
to conduct
further research

217
00:06:51,620 --> 00:06:53,765
quantifying the
ecosystem services

218
00:06:53,765 --> 00:06:55,310
provided by hazard trees,

219
00:06:55,310 --> 00:06:56,600
which are chews on PCCs

220
00:06:56,600 --> 00:06:58,040
property that
were damaged by

221
00:06:58,040 --> 00:06:59,720
the land clearing
and can then

222
00:06:59,720 --> 00:07:02,285
fall onto neighboring
properties.

223
00:07:02,285 --> 00:07:04,310
They provided
suggestions for

224
00:07:04,310 --> 00:07:05,570
updating the
county code to

225
00:07:05,570 --> 00:07:07,190
prevent future damage to

226
00:07:07,190 --> 00:07:09,350
trees on neighboring
properties,

227
00:07:09,350 --> 00:07:10,625
neighboring land clearing,

228
00:07:10,625 --> 00:07:12,260
as well as
recommendations for how

229
00:07:12,260 --> 00:07:14,345
to ensure that
riparian buffers

230
00:07:14,345 --> 00:07:16,670
are preserved for
their urbanization.

231
00:07:16,670 --> 00:07:20,420
Had his back to take
that. Yes, sir.

232
00:07:20,420 --> 00:07:22,100
To conclude this
presentation,

233
00:07:22,100 --> 00:07:24,530
we wanted to express
a Daiichi methodology

234
00:07:24,530 --> 00:07:26,060
can be replicated.

235
00:07:26,060 --> 00:07:27,650
This methodology
can present

236
00:07:27,650 --> 00:07:29,180
opportunities to
further engage

237
00:07:29,180 --> 00:07:30,590
students in meaningful

238
00:07:30,590 --> 00:07:31,880
research while developing

239
00:07:31,880 --> 00:07:33,740
applicable skills that
will serve useful

240
00:07:33,740 --> 00:07:36,155
for future environmental
professionals.

241
00:07:36,155 --> 00:07:37,535
This type of work presents

242
00:07:37,535 --> 00:07:39,110
opportunities for
students to learn what it

243
00:07:39,110 --> 00:07:40,880
means to be better
land stewards and

244
00:07:40,880 --> 00:07:42,350
land management
partners by

245
00:07:42,350 --> 00:07:43,520
presenting the value of

246
00:07:43,520 --> 00:07:45,095
our natural resources.

247
00:07:45,095 --> 00:07:46,070
And we're able to

248
00:07:46,070 --> 00:07:47,210
share the student
projects that

249
00:07:47,210 --> 00:07:49,385
came to fruition
from this research.

250
00:07:49,385 --> 00:07:50,690
And students were
able to build on

251
00:07:50,690 --> 00:07:52,100
this research and advocate

252
00:07:52,100 --> 00:07:53,255
for our natural resources,

253
00:07:53,255 --> 00:07:54,560
which ultimately
can increase

254
00:07:54,560 --> 00:07:57,290
the visibility of land
management decisions.

255
00:07:57,290 --> 00:07:59,120
We believe the efforts of

256
00:07:59,120 --> 00:08:00,380
these students can support

257
00:08:00,380 --> 00:08:01,565
the management decisions.

258
00:08:01,565 --> 00:08:03,620
Like our partners, I
clean water services,

259
00:08:03,620 --> 00:08:04,760
deciding to be plant

260
00:08:04,760 --> 00:08:06,560
over 2 thousand plants to

261
00:08:06,560 --> 00:08:08,420
enhance habitat
connectivity and

262
00:08:08,420 --> 00:08:09,880
serve as a
vegetative quarter

263
00:08:09,880 --> 00:08:11,300
adjacent to the
active flip then

264
00:08:11,300 --> 00:08:13,190
enhancement
restoration site at

265
00:08:13,190 --> 00:08:14,120
Portland Community
College,

266
00:08:14,120 --> 00:08:16,110
Rock Creek campus.

267
00:08:16,120 --> 00:08:18,440
And then we have
included the link to

268
00:08:18,440 --> 00:08:20,000
the student research
projects if anyone

269
00:08:20,000 --> 00:08:22,025
is interested in
exploring their work.

270
00:08:22,025 --> 00:08:24,350
And that concludes
our presentation

271
00:08:24,350 --> 00:08:25,730
and we would like to thank

272
00:08:25,730 --> 00:08:27,380
the audience and
urban ecology and

273
00:08:27,380 --> 00:08:29,390
conservation symposium
for this platform

274
00:08:29,390 --> 00:08:32,310
and we welcome
any questions.
