Human-related factors regulate the presence of domestic dogs in protected areas

摘要: The presence of domestic species such as dogs Canis familiaris in protected areas can cause problems for native a result competition, predation and disease transmission. To improve our ability to design effective control policies we investigated the factors affecting detection dog tracks Mediterranean national park. We across 69 2 × 2 km grid squares Donana National Park south-west Spain used logistic regression models analyse associated environmental human constraints. did not detect away from edges park close settlements (track census effort > 470 km) was correlated with presence. conclude that occasionally enter surrounding area are direct threat wildlife at Park. Management actions reduce effects where feral populations established should focus on spatial extent local settlements, regulation awareness-raising encourage responsible dog-ownership, measures removing un-owned boundaries dwellings, forbidding unleashed public facilities.
