CONCLUSION AND RECOMMENDATIONS

CONCLUDE

We have investigated the matter

ear cleaning _

area

Spring and Autumn National Park is concerned with expenditures

silviculture (D, H, N, biomass...), the result is that the mangroves in the study area are showing signs of degradation and will continue to become more serious in the future . in both quantity and quality. The regeneration of forest plants does occur but is still slower than the rate of degradation.

Modeling results showed a decline in individual density and biomass of

species over time

The species composition in the study area is still quite poor, there are 2 main plant species (2 official mangrove species: Ban chua, Trang and 01 joined mangrove species, Su). The number of Trang species is still absolutely dominant and dense because it is planted for the purpose of retaining soil, blocking waves, and protecting the coast.

The project has proposed forest planning according to the scenario of sea level rise at the time points of 2030, 2050, 2100 with the corresponding area being: 2,042 hectares; 3,623 hectares; 4,732 hectares, divided into 3 phases as follows:

- Period 2011-2030: Maintain strictly protected forest area (1,206 hectares) and increase forest planting and restoration in existing aquaculture areas, by 2030 the area will have 3,623 hectares of flooded forest land. salty.

- Period 2030 - 2050: continue to expand the area of ​​strictly protected forests,

Promote afforestation and forest restoration. By 2050, the region will have 3,623 hectares of mangrove forest land.

- Period 2050 - 2100: expand the area of ​​strictly protected forests, promote afforestation, by 2100 the region will have 4,732 hectares of mangrove land.

RECOMMENDATIONS

Develop a detailed plan on planting and managing mangrove forests in Xuan Thuy National Park

The study proposes planting more new species suitable to the region's climatic conditions.

The study proposes a thinning plan to create space for natural mangrove regeneration.

It is necessary to research and build a bank to store and preserve plant species that once existed and grew in the area.

Develop a legal framework and policy mechanisms to support the conservation and development of mangrove forests

There continues to be research on modeling the effects of environmental factors on growth and development fluctuations of CNM species in all areas across the country.

Continuing Xuan Thuy.

It 's like studying cancer for seriousness _ _
