Ohop Tree Planting-middle school

  1. 1. The First People •The Nisqually Tribe •“Squally-absch”, or “People of the river, People of the grass country”. •Traditionally lived off the land and rivers •Salmon are important to their diet and culture.
  2. 2. European Settlers came…. • Cleared local vegetation • Farmed crops and animals • Ditched creeks
  3. 3. Modern Life….
  4. 4. Our region changed… 1972 1996
  5. 5. How does this affect wildlife?
  6. 6. Ohop Valley Restoration
  7. 7. The Ohop Valley Story  Ohop Creek is the 2nd most important salmon-producing tributary of the Nisqually River.  A century ago, the creek was drained into a ditch. This was done to dry-out the valley for dairy farming.
  8. 8. Restoration Activities • Re-meander stream • Removing old buildings • Removing invasive plants • Replanting the large floodplain
  9. 9. Why Re-meander a stream?  Meander= to follow a winding, bending course. A river is always changing shape due to natural erosion processes. Improves connection with other streams within the floodplain Provides temperature control Creates different speeds of water, giving fish rest areas instead of one fast stream
  10. 10. Ohop Creek Replanting 100 acres along the river. Installing 40 log jams 400 trees
  11. 11. Ohop Creek Realigning ditched channel
  12. 12. Engineered Log Jams Mimicking Nature
  13. 13. Our Purpose Replant native vegetation to re-establish a healthy riparian zone.
  14. 14. 5 Main Reasons We Plant Trees For Salmon A. Roots hold dirt, preventing erosion which can smother the redds within the stream.
  15. 15. 5 Main Reasons We Plant Trees For Salmon B. Large woody debris (LWD) provides pools, resting spots, feeding areas, and hiding spaces from predators.
  16. 16. 5 Main Reasons We Plant Trees For Salmon C. Trees provide shade, keeping stream temperatures low, a necessity for the survival of salmon.
  17. 17. 5 Main Reasons We Plant Trees For Salmon D. Trees provide oxygen, which is good for not only the salmon, but us too.
  18. 18. 5 Main Reasons We Plant Trees For Salmon Lastly… Provide habitat for bugs, which are food for the juvenile salmon! Trees drop leaves, which feed the base of the food chain in the stream!
  19. 19. What is a Native Plant?
  20. 20. Native Plants are Native to our Bioregion!
  21. 21. Red Alder Alanus rubra Red alders can grow to be more than 120 feet tall Have the ability to fix nitrogen, contributing to the abundance of this limited nutrient
  22. 22. Oregon Ash Fraxinus latifolia The Oregon ash is a deciduous tree that can grow over 80 feet tall and live up to 250 years
  23. 23. Balsam PoplarPopulus balsamifera Balsam poplar is a fast growing deciduous tree that can grow up to 98 feet tall. Bees collect resin and use it to seal off intruders, such as mice, which might damage and infect the hive.
  24. 24. Sitka Spruce Picea sitchensis The Sitka Spruce is an evergreen tree that can grow over 340 feet tall and is the largest species of spruce Natives used softened pitch to patch and waterproof boats, harpoons and fishing gear.
  25. 25. Pacific Crab Apple Malus fusca Natives would cook and mash the apples The wood is hard and somewhat flexible and was used to make tool handles, bows, wedges, and digging sticks. The Pacific crab apple can grow up to 30 feet tall and has can look like a multi-stemmed shrub
  26. 26. Red Osier Dogwood Cornus sericea Red osier dogwood is a woody, deciduous shrub with a rounded form and can grow in thickets of up to 3-10 feet Natives sometimes used the branches for basket rims
  27. 27. Twinberry Honeysuckle Lonicera involucrata Twinberry is a deciduous shrub that grows between 6-10 feet with a 6-10 feet spread The berries are incredibly bitter and attract birds, bears, and small mammals
  28. 28. Pacific NinebarkPhysocarpus capitatus Pacific Ninebark is a deciduous shrub that can grow 10-15 feet Natives would use parts of this plant for medicinal purposes
  29. 29. Cascara Rhamnus purshiana Cascara is deciduous and can grow as a shrub up to 15 feet tall or as a small tree up to 50 feet Natives used cascara as a medicine to wash wounds and to reduce swelling
  30. 30. Swamp Rose Rosa pisocarpa Swamp or cluster rose is a deciduous shrub that grows in thickets up to 3-6 feet tall Bears rose hips that attract and provide food for birds and mammals
  31. 31. Rose spirea Spiraea douglasii Rose spirea or hardhack is a deciduous shrub that grows in thickets of 3-12 feet Reproduce from rhizomes (an underground stem) that allows it to grow in thickets
  32. 32. Sitka willow Salix sitchensis A large, deciduous shrub that can reach heights of 25 feet Natives pounded the bark and applied it topically to wounds as a healing agent, ground it to a powder and mixed with cereal to make bread and used it to make rope
  33. 33. Remember, Safety First!  Walk, don’t run.  Stay in sight of the group at all times.  Shovels:  Sharpened regularly, which makes them dangerous.  Never carry shovels over your shoulder.  Tip should always be pointed towards the ground, like walking sticks.
