Forestland connectivity in Romania—Implications for policy and management

摘要: Abstract Forest policies and management rules imposed on forests in Romania provide favourable habitat conditions for many species across forest landscapes. This is empirically proven by the high biodiversity of Carpathians their surroundings. However, they do not explicitly address spatial arrangement patches Therefore, assessment connectivity (inside tracts continuous – i.e. intrapatch also among spatially separate interpatch connectivity) important. To analyze this, CORINE Land Cover data set (2012) available was used. were classified into three size categories considered to ensure survival tree populations short term, medium long term: Interconnectivity Nodes (IN: 1,5 14,9 ha, minimum 30 m width), Habitat Islands (HI: 15,0 ha 499,0 ha, 100 m width) Continuum (HC: over 500 ha with a 200 m respectively. The each patch others around it assessed maximum threshold distance 1 km. Further terms its strength (depending category which connected) quality (size structure resulting connected cluster). Next, distributions main various sizes, vegetation assessed. results showed good between patches, both (85% area included HC class) (92,4% are 12 clusters 10.000 ha; these one comprised 86,7% total area). general, higher mountainous areas than at lower elevations (area patches: 97,5% Norway spruce vs. 63,3% pedunculate oak; strong connection 97,8% 67,2% 98,2% 68,6% oak). These confirm that guidelines inherited from past general. enforcement practices future should conservation forested landscapes national scale routes migration context climate change. as large proportion forestland today state-owned, financial incentives private owners key condition further acceptance major goals met.
