South Seattle College
OP-9: Landscape Management

South Seattle College follows the four-tiered approach to IPM as outlined by Washington State Department of Agriculture. All employees within the grounds department receive annual IPM training to stay informed about new techniques and processes.

Using permaculture and organic growing principles, Community Orchard of West Seattle (COWS) demonstrates several different kinds of non-standard orchard techniques and garden configurations - most of which are based on no-till, polyculture, low-maintenance sustainable food production strategies. As a completely organic orchard/garden, COWS has eliminated the use of inorganic fertilizers and pesticides, fungicides, and herbicides. Central to permaculture are the three ethics: care for the earth, care for people, and fair share. They form the foundation for permaculture design and are also found in most traditional societies. Here are the 12 principles of permaculture as described by David Holmgren. 1. Observe and Interact – “Beauty is in the mind of the beholder” By taking the time to engage with nature we can design solutions that suit our particular situation. 2. Catch and Store Energy – “Make hay while the sun shines” By developing systems that collect resources when they are abundant, we can use them in times of need. 3. Obtain a yield – “You can’t work on an empty stomach” Ensure that you are getting truly useful rewards as part of the working you are doing. 4. Apply Self Regulation and Accept Feedback – “The sins of the fathers are visited on the children of the seventh generation” We need to discourage inappropriate activity to ensure that systems can continue to function well. Negative feedback is often slow to emerge. 5. Use and Value Renewable Resources and Services – “Let nature take its course” Make the best use of nature’s abundance to reduce our consumptive behavior and dependence on non-renewable resources. 6. Produce No Waste – “Waste not, want not” or “A stitch in time saves nine” By valuing and making use of all the resources that are available to us, nothing goes to waste. 7. Design From Patterns to Details – “Can’t see the forest for the trees” By stepping back, we can observe patterns in nature and society. These can form the backbone of our designs, with the details filled in as we go. 8. Integrate Rather Than Segregate – “Many hands make light work” By putting the right things in the right place, relationships develop between those things and they work together to support each other. 9. Use Small and Slow Solutions – “Slow and steady wins the race” or “The bigger they are, the harder they fall” Small and slow systems are easier to maintain than big ones, making better use of local resources and produce more sustainable outcomes. 10. Use and Value Diversity – “Don’t put all your eggs in one basket” Diversity reduces vulnerability to a variety of threats and takes advantage of the unique nature of the environment in which it resides. 11. Use Edges and Value the Marginal – “Don’t think you are on the right track just because it’s a well-beaten path” The interface between things is where the most interesting events take place. These are often the most valuable, diverse and productive elements in the system. 12. Creatively Use and Respond to Change – “Vision is not seeing things as they are but as they will be” We can have a positive impact on inevitable change by carefully observing and then intervening at the right time.

There is a percentage of native plants in landscapes. We consider environmental conditioning for area. We have a mixture of native and non-native in landscapes. Some non-native plants are chosen for maintenance purposes.

Some mulch mow. We also collect leaves from hard surfaces to mulch (they double-grind and collect these) and re-use as weed blocker.

We use a mechanical bobcat then de-icer (salt based environmentally friendly- both granular and liquid). We also use a little sand on road beds and shaded areas. Minimal use of both is required due to local climate.

We have many native species on the grounds such as: huckleberries, blueberries, crab apples, figs, thimbleberries, and blackberries for native wildlife.
