Sustainable Harvesting Laws – Canada has strict forestry regulations requiring companies to follow sustainable harvesting practices. These include selective logging, clear-cutting limits, and reforestation mandates. Mandatory Replanting – By law, forestry companies must regenerate harvested areas through natural regeneration or replanting. This ensures that forests continue to grow and remain productive. Public Land Management – Most of Canada’s forests (over 90%) are on public land, meaning logging is subject to government oversight and long-term sustainability planning. Annual Allowable Cut (AAC) – The government sets an AAC to ensure that only a sustainable amount of timber is harvested each year, preventing overexploitation. Certification Standards – Many Canadian forestry operations are certified by organizations like the Forest Stewardship Council (FSC) and Sustainable Forestry Initiative (SFI), which enforce environmental and social responsibility standards. Natural Regrowth – Boreal forests, which cover much of Canada, are naturally resilient and regenerate through natural processes like seed dispersal and regrowth from cut stumps. Protection of Old-Growth Forests – While some concerns remain, Canada has policies in place to protect certain old-growth forests and biodiversity-rich areas from logging.
呼唤民主党,人呢?出来跟他杠呗
貌似习大大的经济内循环是被川普第一任逼的,结果川普第二任学习,完美闭环了…
我们这也就是灌木丛加草地。几年前也烧了一大片。
怎么可能梳理,砍伐运输成本多高 砍伐森林就是成片砍光,有的给开发商造房子,不造房子就种人工林。
他们很多人都是靠福利的,这下傻眼了,活该。
对你这类小左,看来不把两边脸都抽肿,根本不算抽一次!
黑松(Pinus thunbergii)的生长速度受环境、土壤、水分、气候等因素的影响。一般来说,在适宜的生长条件下,黑松的 胸径(树干直径)每年增长约 0.5 至 1.5 厘米。
幼年期(0-10 年):生长较快,胸径年增长约 1-1.5 厘米。
中年期(10-30 年):生长速度稍减缓,胸径年增长约 0.8-1 厘米。
老年期(30 年以上):生长速度进一步下降,胸径年增长约 0.5-0.8 厘米。
直径30厘米10-20年就可以,100年不是毫无根据无耻造谣?
我看小左的脸皮长30厘米都用不了100年

我看到有数据显示自然生长情况下,黑松需要100年才能长30厘米。人工种植会快一些,也需要20-30年。我查到的数据链接如下,数据来源是中文的,没有看到英文相关数据。不知道你的数据来源是哪里?
而且,30年长成的树砍掉了就没问题了?

这些川总是不会考虑的 他考虑的第一是对他的人是不是有利---涉及直接腐败; 第二是还是attention whore本性,放个大炮仗,吸引注意力,对低智的粉来讲,只要有动静就是进步
骗子治国而已, 和商人没啥关系.
你跟川粉讲多样性? DEI的啊, 川粉哪听得懂.
这人使用语言暴力,可以不这么说话么?太野蛮了。
以前不太信,现在事实摆在眼前啊😯
是开放可以砍,不是让你一下砍完,第一做不到,第二没必要。
但是加拿大森林覆盖率是国土面积的46%,占世界森林覆盖的9%,森林蓄积量为196亿立方米,加拿大是一面砍树(成年树)一面种树,每砍一棵成年树,就要种回一棵小树苗,加拿大林木业是本国最大的出口产业之一,所以有一套完善的采伐规划,并不是随意砍伐或者没有计划砍伐的,我老公的公司专门和木材厂做生意,木材厂也只能在指定区域砍伐,并不是随便找地方可以砍伐树木的。。。。另外加拿大的林木业是给世界140多个国家提供木材输出,其中包括欧盟,美国,中国等,并不是只给美国提供木材。。。。。
因为加拿大木材厂每砍一棵树,就要种回去一颗小树苗,而且只能在指定的区域砍树,树的直径不能超过一定厘米(超大的树不能砍,受法律保护)我老公的公司和北美基本所有的木材厂都有生意往来,他经常去各地木材厂出差,美国也有木材厂,但美国木材的原价就比加拿大高,再加上汇率差额,所以美国木材厂也喜欢买加拿大原木,因为更能挣到钱。。。
