Forest fragments matter: a look into the species richness and diversity patterns of birds in a small, isolated, Protected Landscape in Mindanao Island, Philippines // Nature Conservation Research.

Учреждение особо охраняемых природных территорий (ООПТ) считается критически важным в глобальных природоохранных инициативах, особенно в глобальных горячих точках биоразнообразия, таких как Филиппины. Однако решающая роль, которую играют небольшие ООПТ в сохранении биоразнообразия, часто упускается из виду, что повышает интерес к этой области исследований. ООПТ Инитао-Либертад – один из последних сохранившихся карстовых лесов с естественной растительностью и убежище для сохранения дикой природы на острове Минданао, Филиппины. Однако территория суши этой ООПТ очень мала (около 506 000 м²). Она разделена дорогой и сильно нарушена незаконными вырубками и частыми посещениями туристов. В 2014–2018 гг. была проведена оценка структуры сообщества птиц и выявлены закономерности разнообразия птиц на ООПТ Инитао-Либертад. За 558 230.40 ч. отлова паутинной сетью в двух зонах ООПТ (зона особого режима охраны (ЗОРО) и зона туризма (ТЗ)) в общей сложности было зарегистрировано 814 особей птиц 36 видов, относящихся к девяти трофическим группам. ООПТ Инитао-Либертад имеет высокий (33%, 12 видов) уровень эндемизма, включая девять эндемиков Филиппин и три эндемика острова Минданао. Был также отмечен угрожаемый вид Gorsachius goisagi, отнесенный МСОП к категории уязвимых (VU). Видовое богатство в ЗОРО было выше, чем в ТЗ (p = 0.012), тогда как существенных различий в значениях индекса Шеннона (p = 0.101) и средних значениях коэффициента отлова (p = 0.378) между двумя зонами не обнаружено. Видовой состав и трофические группы не имели значимых различий между зонами ООПТ, ЗОРО и ТЗ (p = 0.939), но значимо различались между ярусами леса (p = 0.001). Таким образом, было показано, что на этой небольшой ООПТ обитает сравнительно разнообразное сообщество птиц, включая виды с ограниченным ареалом и виды с высоким природоохранным статусом. Это свидетельствует о том, что даже такого незначительного размера фрагменты леса являются важной средой обитания для усилий по сохранению птиц, и их не следует недооценивать. Рекомендовано расширить такие исследования на другие фрагменты природных территорий, особенно на те, которые до сих пор не охраняются, чтобы улучшить наши знания о биоразнообразии, углубить понимание динамики биоразнообразия и фрагментов, а также обосновать необходимость защиты других фрагментов лесов.
