Round off values to two decimal places where necessary. Question 1. (25 points) steelhead trout in pismo creek and the crp. In 1996, the california department of fish and game implemented a steelhead restoration and management. Steelhead are a good indicator of the health of the aquatic environment because they require clear, clean water, and they use all portions of a river system. It turns out that steelhead reside in pismo. Creek, surviving the dry summer months in deep, shaded pools. An obstacle in the way of restoring the local. Steelhead population in pismo creek is soil erosion from farming row crops in the watershed area overlying. Erosion causes channelization of creeks, which essentially whisks water to the ocean from the deep pools that provide summer habitat for steelhead. The u. s. conservation reserve program (crp) subsidizes farmers to convert highly erodible and highly sensitive cropland to conservation uses.
