10-4 How Should We Manage and Sustain Parks and Nature Reserves?
National Parks Face Many Threats! • More than 1,100 major National Parks located throughout 120 countries. • Too small to substain large animal species. • Invasion from nonnative species that reduce populations of native species and worsen ecological disruption.
Developing Countries • Parks possess the greatest biodiversity of all parks. • Sadly, only about one percent of these parklands are protected. • Park services with little money and few personnel lead to illegal activities like poaching, logging and mining.
Case Study Pg 234 • Stresses on US Public Parks • US national Park System includes 58 major national parks. • Popularity is one of the biggest problems.(Not from 1960-2007 where visitors more than tripled.) • Unpleasant nuisances during summers like long backups, unpleasant noises, congestion, eroded trails , stress, and machinery like dirt bikes and dune buggies have led to a decline of popularity in many Parks.
Case Study continued. • Migration and Introduction of nonnative species also damage parks. • Examples- European Wild Boars introduced for hunting in 1912 threaten the vegetation in Parts of the Great Smoky Mountains National Park • Non Native Mountain Goats in Washington State’s Olympic National Park speed up soil erosion and trample native vegetation.
Nature Reserves Occupation • Only 12% of earth’s land area is protected strictly or partially in nature reserves, parks, wildlife refuges, wilderness and other areas • The 12% is very misleading because only about 5 % is strictly protected from harmful human activities. • That means that 95% of the earth’s land is for human use.
Solutions(National Parks) • Integrate plans for managing parks and nearby federal lands. • Add new parkland near threatened parks. • Buy private land inside parks. • Locate visitor parking outside parks and provide shuttle buses for people touring heavily used parks. • Increase federal funds for park maintenance and repairs. • Seek private donations for park maintenance and repairs. • Limit the number of visitors in crowded park areas. • Increase the number of park rangers and their pay. • Encourage volunteers to give visitor lectures and tours.
Designing and Connecting Nature Reserves • Large reserves substain more species and provide greater habitat diversity. • They also minimize exposure to natural disturbances like fires, hurricanes, invading species and human disturbances. • “Buffer zone” concept use to design and manage nature reserves
Costa Rica: A Global Conservation Leader • Super Power of diversity • Estimated 500,000 plant and animal species • Government has played a substantial role in the reduction of deforestation by paying land owners to maintain or restore tree coverage. Between 2007-08 they also planted nearly 14 million trees to help preserve the country’s biodiversity.
