Whatcom
Creek Trail
11-16-13
By: Erin Kline
The Trail


Whatcom Creek trail
lies alongside
Whatcom creek
(hence the name).
The site was
renovated in 2008
and now provides a
beautiful habitat for
trail goers to view
and nature to
flourish.
How the day began...
 My

day began
when I arrived at
the trail and was
greeted by a team
from L.E.A.D and
the Nooksack
Salmon
Enhancement
Association.
The Goal
 The

goal of the day
was to enhance
wildlife and salmon
habitat along the
creek by planting
native species,
removing invasive
species, and
spreading mulch
Invasive Species
 Some

of the
invasive species we
removed included:
 Himalayan
Blackberry
 Teasel
 Horsetail Ferns
What are invasive species?
 Non-native

species
 Introduction into ecosystem is likely to
cause environmental harm
 Tend to be an aggressive species that will
grow and reproduce rapidly, ultimately
causing major disturbance to the
ecosystem in which they are present
Why are invasive species bad?





Out-compete native
understory vegetation
Prevent young native
trees access to the sun
which is necessary for
germination
They can grow into
dense, impenetrable
thickets that may
inhibit larger wildlife
access to resources
such as water and
shelter
Mulching
 Mulch

is essentially
a protective layer
of a organic
material that is
spread on top of
the soil.
 We placed
mounds of mulch
around young
trees.
Benefits of mulch


Provides protection for
native species from soil
erosion and
compaction



Increases water
infiltration



Helps to maintains a
stable soil temperature



Prevents and reduces
weed growth
How does this relate to class?
 1.

Genetics and evolution
 Biodiversity

 2.

Ecosystem ecology
 Competition

 3.

Human impact
 How

we hurt
 How we can help
Genetics and Evolution







It has been emphasized throughout the quarter
that biodiversity is the well-spring of life.
Biodiversity increases overall ecosystem health
and productivity.
A diverse ecosystem is able to prevent and
recover from various obstacles whether they be
natural or of human cause.
By removing invasive species and replacing them
with native species, we contribute to the
maintenance of a biodiversity within this particular
ecosystem.
Ecosystem Ecology




As discussed in
lecture, competition
between species is a
lose-lose situation.
In this situation,
invasive species
outcompete native
species. This results in
decrease in native
species, and a loss of
biodiversity.
Human Impact






Humans have astronomical influence on the
.
environment.
We directly and indirectly pollute, destroy and
pose as obstacles for ecosystems to
overcome.
Humans play a role in the introduction of
invasive species. As a result, it is up to us to do
what we can to alleviate the stress that
invasive species pose to healthy ecosystems
by removing invasive species and promoting
native species
The BIG IDEA
 “Humans

influence ecosystems for the
better or for the worst.”
 By taking 3 hours out of my day to give
back to the environment that has given
so much to me, I would like to think that
this project serves an example of how
humans can help to influence ecosystems
for the better.
Thank you!
