Mulching our natives!
Reflecting on Rock Creek
Rock Creek Middle School @ Rock Creek on 4.18.2013
Rock Creek Middle School is dedicated to restoring our watershed!
We spent the evening mulching some native species to help add nutrients to the soil and to suppress weeds. These mulch “donuts” will also help the plant retain water in the warm summer months! However, while mulching our native plants, it was impossible not to notice (and remove!) all of the invasive species that were creeping in. Armenian Blackberry, Teasel, and Robert’s Geranium were some that we found – just to name a few! At the end of the day, we took some time to reflect on our work at Rock Creek and how we help improve the health of our watershed for future generations. We left feeling accomplished and excited for our next outing!

“Never doubt that a small group of thoughtful, committed citizens can change the world” – Margaret Mead
Although few, Rock Creek Middle School is always excited and ready to steward Rock Creek! With shovels in hand, we took down Blackberry and dug up lots of gnarly roots. We also had time to chat about our native Red Currant and Oregon Grape before we planted 7 of them! It was a productive day that will make Rock Creek healthier for generations to come! Thank you for your dedication Rock Creek Middle School!

Rock Creek Middle School formed an after school Green Team club that would dedicate some of their time to taking ownership of Rock Creek down the street from their school. SOLVE was excited by their enthusiasm and for their first outing to Rock Creek!
We had a full afternoon of activities planned. First, we played a game of riparian metaphors. What is that you might ask? Well, we pulled items out of a bag and came up with metaphors for what they might represent in a healthy riparian zone! For example, sunglasses could be a metaphor for shade to keep the water cool and oxygenated. We came up with clever metaphors for strainers, camouflage shirts, yogurt containers, bird houses, and more!
After we exhausted our creativity, we learned how to identify native plants by looking at their lateral bud arrangement. For example, Red Flowering Currant has alternately arranged lateral buds while Snowberry is one of our opposite friends! Once we could correctly identify the native plants waiting to go into the ground, we grabbed some Red Currant, Elderberry and Oregon Grape and planted 18 plants!! Not only did we plant plants, but we also dug invasive Blackberry roots to give our plants a leg up on the competition.
As the sun went down it was time to call it a day – a very successful one at that. See you next time Green Team!
SOLVE’s Annual Women in Science day will be held at Glen Otto Park in Troutdale on March 23rd from 9-1. Girls – Are you interested in exploring a career in science? Come chat with mentors currently in the science field over breakfast! In the afternoon we will be planting trees up the road at Beaver Creek!

Last week, students from Rock Creek Middle School came out for their last visit to their eponymous creek to do some macroinvertebrate surveys. They had some help from another Green Team for their survey: students from Clackamas High School. Clackamas High School students have been doing macro surveys since October and they even gave an outstanding presentation on their findings from the past year at our Green Team East Side Student Summit, so the Rock Creek Middle School students could not have found better mentors for this activity. The Clackamas Green Team first talked about why doing macro surveys is important by explaining how this survey can give us a good indication to how healthy this creek actually is. They explained that it can be better to look at the invertebrate population in streams rather than looking at chemistry and temperature (which can frequently fluctuate). These bugs live in the stream all the time and are subject to these fluctuations. Since some types of invertebrates are very pollution sensitive and others are more pollution tolerant, looking at the types and numbers of invertebrates in the stream can give a fairly accurate indication of stream health. Then the Rock Creek students split off with their High School mentors to go see what they could find.
It was exciting for everybody because a lot of different kinds of macroinvertebrates were found including pollution sensitive ones like mayflies, stoneflies, and green rock worms, a kind of caddisfly! The presence of these indicate that the stream has not been too compromised by pollution. The restoration work that both Rock Creek Middle School and Clackamas High School have done on Rock Creek in planting natives, and removing invasive plants, all contribute to reducing the pollution flowing in the creek by reducing the amount of sediment, heat, and some chemical pollutants like heavy metals. During their last visit of the school year, it was nice to see that the effort that these students have done all year in trying to restore the Rock Creek Watershed is paying off in keeping the stream healthy.
SOLVE Green Team and the Rock Creek watershed thank you both Rock Creek Middle School and Clackamas for all of your hard work this year!
Thanks to Water Environmental Services for funding this project!

A lot of the work at our sites is suddenly becoming relevant as the skies are drying up and the grass is growing much longer. This was especially evident at Rock Creek on Monday when Rock Creek Middle School came out to help improve the riparian ecosystem.
When students got to the site, they noticed that the grass growing around the plants seemed to have grown a full foot in the week since they had visited the site two weeks ago. Already many of the plants that the Rock Creek Middle School Green Team had planted this winter were dwarfed by the grass and fighting for the precious sunlight. To encourage these young native plants to thrive and grow into a nice healthy riparian ecosystem, the Rock Creek Middle School students got right to work placing coffee bags around the base of the young native plants. These coffee bags are made of jute – a biodegradable grass – and when staked around our native plants, they suppress the resource-stealing grass from growing right next to the native plants. Students also spent some time mulching the recently coffee-bagged plants. As the weather continues to get drier, having a nice layer of mulch above the roots will be really helpful in preventing these young short-rooted plants from drying up before they really get established.
After they left the site, their hard work was evident: each native plant had their own growing and breathing (and photosynthesizing?) space, like a little sanctuary island in a sea of tall menacing grass. With their help this new site is definitely on the way to developing into a nice native habitat. Rock Creek thanks you, Rock Creek Middle School Green Team!
A brand new trimester of energetic students from Rock Creek Middle School joined us today at Rock Creek. Charlie(SOLVE) taught students all about why past students and community volunteers have worked so hard to plant native trees and shrubs along the creek, providing enhanced habitat and better water quality. Students protected those new plantings with a fresh layer of Douglas Fir mulch.
Mulching our plantings is a critical part of the restoration process. The mulch mimics growing conditions in a healthy riparian forest. A healthy forest has a natural layer of ‘mulch’ (leaf litter and decaying organics, or duff layer) that provides a protective covering for immature plants.
ADVANTAGES OF MULCH
- An effective and safe way to reduce weeds.
- Reduces evaporation resulting in less watering.
- Keeps soil temperatures cooler in summer and warmer in winter.
- Using organic mulches, results in the soil benefiting from addition of nutrients as the mulch decomposes. This helps create good soil structure as it greatly increases the biological activity in the soil (especially earth worms and other beneficial microbes).
- Protects the soil surface from the compacting effect of rain.
- Organic mulch decomposes over time and this benefits the soil by the addition of nutrients, especially nitrogen
Students also got a chance to critically think about all the benefits of a healthy riparian corridor by playing a Riparian Metaphors game. Students partnered up and pulled out objects from a bag then worked together to think how that object represents a healthy riparian cooridor.
Some objects –
A piggy bank with leaves sticking out – Healthy riparian zones have vegetated banks!
A sponge – Healthy riparian zones act as a sponge for polluted stormwater.
A camo shirt – Healthy riparian zones can offer cover for animal escaping from predators
Thank you Rock Creek Middle School!
On Monday, while most students might be groggily trying to readjust to the school day schedule from the weekend, our Rock Creek Middle School Green Team students had the opportunity to wake up in the beautiful February sunshine (something seems wrong with that last sentence…) Not to mention, they also got some great work done in their community.
When they arrived to the site, the enthusiastic students got right to work. While some students learned how to plant native riparian and wetland plants along the stream and began putting them in the ground, others were helping maintain the already planted plants by placing coffee bags around them. These coffee bags are biodegradable sacks that were used to transport raw coffee beans that were donated by coffee roasters for this cause. When placed around a plant, they will suppress invasive species from growing right next to these young natives and prevent them from stealing resources such as water, sunlight, and nutrients. Overall, nearly 40 plants were planted and many more were protected with coffee bags, an impressive feat for their brief visit to the site.
Thanks to these kids, Rock Creek is already looking more beautiful with the prospect of a healthy riparian zone!
