Status and trends in global primary forest, protected areas, and areas designated for conservation of biodiversity from the Global Forest Resources Assessment 2015

Abstract

a b s t r a c tThe global community has recognized the importance of forests for biodiversity, and has prioritized the preservation of forest biodiversity and ecosystem functions through multiple multilateral agreements and processes such as the Convention on Biodiversity's Aichi Targets and the Millennium Development Goals. The Global Forest Resources Assessment (FRA) provides one mechanism for tracking progress toward such goals in three particular areas: primary forest area, protected forest areas, and areas designated for the conservation of biodiversity. In this paper, we quantify current area and trends in forest areas designated for the conservation of biodiversity, protected forest areas, and primary forests by country and biome; and examine the association between total forest area and measures of protection, per-capita income, and population. The overall findings suggest that countries are increasingly protecting forests of ecological significance at the global scale (7.7% of forests were protected in 1990 rising to 16.3% in 2015), with a strong upward trend in protected areas in the tropical domain (from 12% in 1990 to 26.3% in 2015). However, primary forest area has declined by 2.5% globally and by 10% in the tropics over the period 1990-2015 (using data for countries that reported in all years). Given that many species in the tropics are endemic to primary forests, losses in that climatic domain continue to be of concern, although the rate of decline appears to be slowing.Using multiple regression analysis, we find that a 1% increase in protected area or area designated for biodiversity conservation within a country is associated with an increase in total forest area in that country of about 0.03% (p < 0.05). A 1% within-country increase in population density and per capita GDP are associated with a decrease in forest area of about 0.2% (p < 0.01) and an increase in forest area of about 0.08% (p < 0.05) respectively. Our findings also indicate that, since FRA is used as one mechanism for tracking progress toward goals like the AICHI Biodiversity Targets, country correspondents may require additional assistance toward reporting on primary forest, protected forest, and biodiversity conservation statistics.Ó 2015 Published by Elsevier B.V.

"Patterns of Forest Loss in One of Africa’s Last Remaining Wilderness Areas: Niassa National Reserve (Northern Mozambique) "

“…We found that NNR lost > 100 km 2 of forest cover amounting to ~ 1 per cent of its aggregated forest extent. This may appear substantial, but is much lower than the 3 per cent of forest cover lost in protected areas globally during the same time period (Heino et al, 2015;Morales -Hidalgo et al, 2015). Our findings are also particularly encouraging in the African context, given deforestation rates on the continent are five times higher than the global average (Tranquilli et al, 2014), and there are many examples of protected areas in Africa losing much more forest cover within their boundaries (Bowker et al, 2017;Allan et al, 2017;Sassen et al, 2013).…”

Watersheds and Trees Fall Together: An Analysis of Intact Forested Watersheds in Southern Patagonia (41–56° S)

“…Forests with limited human intervention, whether "pristine", ancient or old growth, are a limited and diminishing feature of modern landscapes [1,2]. They are essential in terms of conserving biodiversity, climate change mitigation, or as reference systems for forest management or restoration [3].…”

Carbon Emissions from Deforestation and Degradation in a Forest Reserve in Venezuela between 1990 and 2015

“…The loss of biodiversity is perhaps the most frequently addressed consequence of deforestation in tropical forests [12,13]. However, these ecosystems are also important reservoirs of carbon with averages between 200 and300 Mg C ha −1 in the aboveground biomass (AGB) [14].…”
