2. Forests, Fisheries, and Biodiversity Gaiser Life Science

3. Know How can we conserve natural resources? Evidence Page # “I don’t know anything.” is not an acceptable answer. Use complete sentences. After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond. Draw before and after pictures of clear cutting and selective cutting.

4. Clarifying ?s Information Page # Forests, Fisheries, and Biodiversity resource- something that contains valuable materials Example: forests, bodies of water renewable resource - a resource that is replenished for future use Example: reforestation - cutting down all trees in a given areaclearcutting - cut down some trees while leaving a mix of tree species standing sustainable yield Selective cutting - the amount of the resource that can be harvested without reducing the future supply Sustainable wood?Certified lumber - labeled as sustainable – wood is replanted as it is harvested fishery- an area with a large population of valuable ocean organisms Sustainable?Limits - amount and size allowed Methods - type of gear allowed Aquaculture - fish farms biodiversity- number of different species in an area affected by area, climate, and niche diversity (habitat diversity)

5. Clarifying ?s Information Page # Forests, Fisheries, and Biodiversity Summary: - a species that influences the survival of many other species in an ecosystem keystone species Example: sea lions affecting salmon runs in Columbia River Healthy population Gene pool diversity (adaptive traits) Example: golden toad extinction- disappearance of all members of a species - this is increasing ! endangered- in danger of becoming extinct Example: Spotted Owl and the lumber industry Why is this important? 1. Economic value - resources and ecotourism 2. Ecosystem value - all species are connected Example: polar bear threatened- could become endangered 3. Pollutioncauses1. Habitat loss2. Poaching4. Invasive species FYI: Point Defiance polar bear rehabilitation and repopulation program
