Human activities contribute to habitat loss and fragmentation in the temperate rainforests. The Democratic Republic of the Congo used REDD funds to create an online National Forest Monitoring System that tracks and maps data on logging concessions, deforestation in protected areas, and national forestry sector measures. While groups like Rainforest Relief aim to stop rainforest destruction by persuading consumers to purchase sustainable woods, other groups like the World Wildlife Fund are hoping to do so by an increased focus on conservation.

Given the recent census which claims some 3,000,000,000,000+ trees world-wide, this rate would equate to an overall population increase of ~0.001% per year (less, if were counting total biomass), and that only if the rest of the world maintained an even balance which, sadly-yet-unsurprisingly it does not, resulting in the net LOSS of about 10,000,000,000 trees world-wide (~0.3%) every year despite the U.S. effort. Sunlight strikes the tropics almost straight on, producing intense solar energy that keeps temperatures high, between 21 and 30C (70 and 85F). 0.5 tons = 1,000 pounds = approximately one 8-tall white oak tree measuring 8 across at its first branching.

It wont matter if it was a positive impact or not. Fishing of intertidal shellfish intensified in the area over the past 6,000 years, resulting in the accumulation of deep shell middens, in some cases more than five metres deep and covering thousands of square metres of forest area. Also interesting is their definition of forest land: Land at least 120 feet (ft) (37 meters[m]) wide and at least 1 acre (0.4 hectare) in size with at least 10-percent cover (or equivalent stocking) by live trees including land that formerly had such tree cover and that will be naturally or artificially regenerated. IOW, a typical suburban-to-rural plot of land with a typical number of trees on it is officially defined as forest land, and thus subject to their oversight.
