Water World

In the mornings I run along the forested part of Terwilliger in southwest Portland. About twice a year, people wearing haz-mat suits spray herbicide in the park to kill invasive plants. Within a day or two of the spraying session the sidewalk is littered with the corpses of small animals such as moles and mice.

I have noticed this phenomenon over the last few years but it wasn’t until a recent run that it occurred to me that, in the same area where the sprayers were required to wear protective gear, including face masks, I was clad only in shorts and a t-shirt.

If the chemicals being used are harmful enough to warrant protective clothing and kill rodents, what does this mean for the health of our water supply?

We in the Pacific Northwest enjoy unusually temperate and mild weather, and in a typical year we experience months of rain. As that rain falls on land it seeps into groundwater carrying whatever particulates it comes in contact with along with it.

The likelihood of herbicidal residue being carried to our water supply through the watershed is high.

As I contemplated the mortality rate of rodents I also felt a rush of gratitude for organizations like the Friends of Tryon Creek, who I work for, that strive to do something to combat the problem of water quality degradation.

Piles of ivy pulled by Friends' volunteers

The Friends’ environmental education and stewardship programs are intended to connect people to the natural world by engaging them with hands-on opportunities to explore our relationship to the planet. Surely “We are all connected”, seeing as how we are just as much a part of nature as the tree that blossoms in the spring, the bird that flies south for the winter, and the mole that seeks cover along Terwilliger Boulevard. To truly appreciate that fact means understanding that our actions impact the world around us in an immediate sense, and those same actions can affect us down the road.

I circle back to the issue of water quality. Spraying herbicide impedes weed encroachment – while adding toxic chemicals to our ground water. That reality inspires the Friends to explore ways to keep our watershed healthy, such as inviting volunteers to pull ivy in the park every Saturday (elbow grease is a great alternative to chemicals!) and bringing the Backyard Habitat Certification Program to Lake Oswego. The BHCP gives property owners the tools to provide habitat for wildlife, reduce water usage and the need for chemical applications, and use native plants to reduce the amount of pollution in runoff to waterways and streams.

Community makes National Public Lands Day a smashing success at Tryon Creek

Lewis and Clark students and community members mug for the camera before hitting the trail to pull ivy

Saturday, September 29th, was National Public Lands Day. It is the largest volunteer event of its kind in the country, as thousands of volunteers show their support of public lands by participating in stewardship activities from coast to coast. The Friends of Tryon Creek were pleased to host just such an event at Tryon Creek State Natural Area. Volunteers rolled their sleeves up and got their hands dirty pulling ivy in the park from 9 a.m. to noon.

REI's Gayle Hoybook distributes free tees to volunteers.

REI was a great supporter of the event. In addition to providing stewardship volunteers with awesome free t-shirts, they served snacks and beverages (to keep their strength up. Those ivy pulls are a lot of work!). The Friends' tip our hats to REI and their strong support for the Friends' environmental stewardship and conservation programs.

3rd & 4th grade Girl Scouts lend a hand doing stewardship at Tryon Creek

Volunteers big and small lent a hand at the event, including Girl Scouts from Troop# 45660 who attend Arco Iris Spanish Immersion Charter School in Beaverton. Their troop leader, Regan Schutz, noted that her group "had a lovely time, and our guide was amazing.  The girls were really interested in learning more about why English Ivy is so destructive to our forests, and they absolutely put their best glove forward when we got down to pulling!  It's amazing how empowering it is to actually get down and work--easy to forget what it's like to be 8 and 9 years old.  Working together for something bigger than themselves, I really felt a shift that day in our (relatively new) troop!" Way to go, Girl Scouts!

The National Public Lands Day stewardship effort at Tryon Creek was very successful. "We had a fantastic turnout of volunteers", says Sarah Kreisman, Volunteer Coordinator for the Friends of Tryon Creek. "It is so wonderful to see how much our community values their public lands."

Thanks Volunteers! We couldn't do it without you!
