Is There Any Old Growth Forest Left? [14 REPLIES FOUND]

About 20% of North American forests were permanently cleared to allow agriculture or other purposes, mostly within the past two centuries (Bryant et al. 1997). Forest cover in the United States is currently stable according to Matthews 2000); however in many lower 48 US states and parts of southern Canada, the remaining forests are subject to significant human disturbance, and they do not have the same level of ecological integrity. As human populations Forest fragmentation continues to increase, and forest degradation is a constant problem. A result was the disappearance of vast areas of old growth forest. A USA-FS 2000 estimate shows that only 7% of the forest cover is made up of stands of centuries-old forest.😁 [1]
A second problem is that the annual allowable cut (or AAC) for the entire province of logging, which amounts to far more than it should, is too high. Logging companies are doing too little, and too quickly. Another way of putting it is that rotation ages are too short: instead of cutting on a 400-year rotation (as is the natural age of many coastal old-growth forests between major forest fires or hurricanes), for example, we’re cutting on a 50-year rotation on the coast (I.e. For 400, it’s eight times faster year old stands). It is leading to the conversion of older, structurally more complicated forests into younger age categories, which do not have the structural features required for older forest species and are dependent on them. For human communities, overcutting also results in the “fall-down effect”, where there is a long-term diminishment in the available wood supply as the forest age classes get younger and the timber volume per hectare correspondingly diminishes. More forests older than 50 years old have more wood per hectare than the ensuing second-growth forests that replace them. These massive layoffs result in huge losses in the forest industry. This includes the BC interior and the coast for the last 20 years. For a forest industry to be sustainable, it is essential that the cut rate is drastically reduced.

Tongass National Forest houses some of the best wildlife in America. oldest trees on earth — many of them dating back more than 800 years. Cedar, western and Spruce hemlock trees They reach more than 200 feet up the sky, and are nearly 12 feet wide at their chest. The trees are a symbol of Southeast Alaska’s temperate rainforest, home to 30 percent of Earth’s total. They also represent one of nature’s last outstanding wonders in biodiversity and natural wealth. Here, some of the rarest wildlife on earth abounds — bald eagles, grizzly bears, Alexander Archipelago wolves, the Goshawk and the Marbled Murrelet. The Icy Straight is fed by ancient glaciers. This winding river delivers three times more essential organic carbon to oceans than the Amazon River, which supports lush marine life. life from krill to sea There are many salmon species, including lions and whales. Exploring the Tongass can be a short hike or a deep wilderness trek, but the time to visit is now, as the forest’s timber harvesting plan threatens the remaining old-growth trees and the health of the wildlife habitat.

The tropics contain just under a third of the world’s forests, but tropical trees hold half of the carbon stored Globally, there are more than 1.2 million trees. WRI analysed Global Forest Watch data and found that between 2019-2020, 4.2 Million Hectares of tropical old growth rainforests had been lost. This resulted in 2.64 gigatons added to the atmosphere. Although many do not see the direct effects of the loss of old growth forests, all people feel their contribution to climate change.

As insane as this sounds, it is impossible to know how much older growth America has left. There are many agencies and scientists who have their own ideas of how to determine the exact amount. Generally speaking, the term “old growth” is a forest that contains trees many hundreds of years old, and sometimes even thousands. Even though there may be agreement about a particular definition, minor differences in methods for inventorying old-growth forest stands can cause major discrepancies. According to the National Commission on Science for Sustainable Forestry’s (NCSSF), there are major discrepancies in methods used for inventorying old growth forests. Changing World.
