- In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals.

Land managers have a responsibility to listen to local people's perspectives. 2. Conservation actions are difficult to coordinate between countries. 3. International organizations provide technical and financial support to developing countries. 4. Train and hire local people to work in protected areas.CER SCENARIO #1 This ecosystem is being affected by the development of a neighborhood. Acres are being cleared for building homes and roads. The people who have already moved in are complaining about the foxes that have been going through their yards and have even tried to catch small cats and dogs as prey. It was decided that the foxes would be trapped and relocated far away from the new neighborhood. PROMPT: WRITE A CLAIM STATEMENT ABOUT WHAT COULD HAPPEN TO THIS ECOSYSTEM WITH THE REMOVAL OF THE FOXES. CLAIM: EVIDENCE: REASONING:
- Site A Site B Site A7 Species Site B = 5 Species *A*+* + Site C7 Species A Site C A vs B = 8 species B vs C = 6 species A vs C = 10 species A developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision? Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. Site C has more unique species in it than either Site A or…Graph Analysis - Predator-Prey Graph Isle Royale National Park on a remote island was established in 1940, and designated a wilderness area in 1976. The only mode of transportation available is by boat or seaplane. Moose first arrived at Isle Royale around 1900. The moose population tends to increase in years with mild winters, early spring green-up, abundant winter forage, low wolf numbers and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from Canada in 1940. Disease has also influenced the wolf population. Between 1980 and 1982, the wolf population declined from 50 to 14, due to canine parvovirus.

- Mimicry occured in nature as species tahe advantageous characteristics from other species to help them survive. As humans, we have also taken this idea of biomimicry and used nature as a design inspiration to sustainably solve human problems. some examples include: whale fins as wind turbines, shark skin materials for marine vessels and swimwear, burrs stick to animals and velcro, water collecting beetles and environmental application. Questions 1. Identify a real world challenge and think about potential designs to solve or help with this challenge. 2. research nature's models - what biomimicry can we see in nature for this challenge? 3. describe a model that could aid in the real world issue and have potential sustainable application.Topic: Mount Baker-Snoqualmie National Forest/Spokane District Leases in Washington What environmental impacts are significant?
