We know that forests are important to all life on the planet. They have often been referred to as the ‘lungs of the earth', a reference to the fact that they produce vast quantities of oxygen - which is essential for respiration for so many forms of life. They also take up carbon dioxide and ‘fix' it into complex organic molecules - from starches, to cellulose and lignin. Thus, the carbon is locked away for months, years or even millennia. The equatorial forests of Brazil and Sumatra are species rich, incredibly diverse, but deforestation and the expansion of agriculture are threats to many biodiverse, forested areas across the world.半岛登录平台网址下载安装手机版如此多森林和林地被砍伐后,现在有运动种植数以百万计树(遍及世界 ), 以努力减缓气候变化,英国则从极低基数提高树覆盖率。 悲哀的是,二十世纪英国林业大都以单树化为主(用于木材生产 ) 。树上布置大站或密室-使用Scottes Pine、Larch和Sprus这些种植园不仅缺乏生物多样性,而且容易发生大规模虫害和极端天气事件半岛登录平台网址下载安装手机版林地和林树种类繁多,不仅健康,而且显示更大的生长量和固碳量半岛登录平台网址下载安装手机版They are more resilient. The diversity of trees ensures the each species accesses slightly different resources from the environment - from soil minerals, water and light. Diversity means that trees of the same species are less likely to be clustered together so pest and pathogen outbreaks are less common or less severe. One area that has undergone an extensive and diverse planting regime is Norbury Park Estate (near Stafford). Since 2009, over 100 different tree species have been planted, and the woodlands can now produce 1500 tonnes of new wood each year, and harvest 5000 tonnes of carbon dioxide from the air. Not only can diverse woodlands / forests fix carbon, supply harvestable timber but they also offer areas for rest and relaxation.半岛登录平台网址下载安装手机版虽然不可能种植`即时'森林或林地,但有可能种植各种树和树丛物种,这些树和树丛将逐步生长成熟形成多样性和丰富物种区。 查尔斯·达尔文多年前曾表示, “ 更多生物在结构、习惯和构造上越能支持越多,他们在结构、习惯和构造上越有差异 ” [自然选择物种源, 1859年] 野生动物林管理-见此N.B.打开PDF
