Using Forest Germplasm Resources Storage Repository to “return†rare and endangered tree species
The use of tree germplasm resource conservation repositories to carry out the protection of forest germplasm resources is the core of maintaining the forest species gene bank and is also an important guarantee for maintaining biodiversity. However, in recent years, due to human activities, it has brought irrevocable forest germplasm resources. Destruction has caused a sharp decline in the resources of wild tree species, limited living space, and some are facing the danger of extinction. Therefore, the use of forest germplasm resource conservation repositories to allow these rare and endangered tree species to “return†is a must for the time being.
There are two important roles of the forest germplasm resource conservation repository. One is to preserve these rare and endangered tree species as seeds rather than extinct. The second is to increase the utilization rate of elite seeds and effectively protect these forest tree germplasm resources. Based on the above, we will actively promote the rational use of forest germplasm resources. In the past few years, the Forest Germplasm Resource Conservation Repository has achieved remarkable results in rescuing forest germplasm resources. Therefore, conservation of rare and endangered tree species germplasm resources is now underway using the Forest Germplasm Resource Conservation Repository to provide a “return†for rare and endangered tree species. An important opportunity.
At present, many of China's rare and endangered tree species are distributed in state-owned forest farms, forest parks, and nature reserves. Therefore, to ensure the timely protection of these rare and endangered tree species, the first is to do a good job of protection in situ, through the establishment of protected areas, and Relying on the conservation of forest germplasm resources to carry out preservation work, effectively improve the protection effect of rare and endangered tree species. In addition, the application of forest germplasm resource conservation libraries will also help the follow-up work. For example, the forestry department will conduct research and breeding of these rare and endangered tree germplasm resources, and will plant them in natural distribution areas. Expand its population, gradually release its endangered status, and promote the return of rare and endangered tree species.
