Study on the Construction of National Forest  Conservation Basein Daming Mountain Reserve  in Guangxi

Farmers living in the near by forest villages fullfilled their living needs mainly through exploiting the forest resources. Controlled forest exploitation created serious forest degradation. The annual forest degradation rate was 2 to 6 million hectares. In this relation the objectives of this study were to asses the relationship of farmer’s characteristics and their competencies in forest conservation. The population of this study was four hundreds farmers living in 12 village near the national forest park. Data was collected from may to october 2005. Data obtained were analized by Kendall W Concordance procedure and SEM. The result pointed out that farmers lacked competencies in both farm and forest conservation.

First Time

In this paper we improve the morphological description of the tree cricket Neoxabea brevipes Rehn, 1913 and a new occurrence record for the species at the São Francisco de Paula National Forest Conservation Unit, State of Rio Grande do Sul, southern Brazil. Morphological characterization is provided together with illustrations emphasizing the most significant diagnostic features, such as the metanotal gland, abdominal specializations and phallic sclerites. The calling song was field recorded, comprising a continuous trill with dominant frequency of 3.6 kHz (19.7°C). The karyotype was described for the first time to Neoxabea Kirby, 1906, including diploid number of 2n=26, with two sexual chromosomes.

Long Period

The inventories on sand flies are usually conducted for a long period in leishmaniasis-endemic regions. Thus, there is little data on the sand fly fauna in areas where no leishmaniasis cases have been reported. Therefore, we conducted an inventory to study the sand fly fauna in the National Forest of Rio Preto (NFRP). We carried out a brief inventory by using four CDC light traps in 2009 during winter and summer. We collected 1,403 sand flies belonging to 11 genera and 22 species. As expected, we did not find in the NFRP region sand flies species that have been reported as vectors of Leishmania. However, we found some species of sand flies with few records and that rarely have been reported in southeastern Brazil. Nevertheless, the diversity and species richness of the sand flies in NFRP were similar to those reported in other Atlantic Forest conservation areas. Hence, we drew the following conclusions: (i) it is necessary to carry out inventories not only in leishmaniasis-endemic areas but also in areas with no records of this disease; and (ii) brief inventories can be useful in describing the sand fly fauna in such areas.

Trade Offs

We employed a forest ecosystem model (SIMA) to study how the changes in forest conservation area and management affect the volume growth, harvested amount of timber, carbon stock, and amount of deadwood in Finnish boreal upland forests under current and changing climates (RCP4.5 and RCP8.5) over 2010–2099. Simulations were carried out on National Forest Inventory plots using three different forest conservation scenarios (baseline and 10% and 20% increases of conservation area) and three thinning regimes (baseline and maintenance of ±20% stocking in thinning compared with recommendations). An increase of forest conservation area increased the volume growth, carbon stock, and quantity of deadwood in forests, as did the maintenance of 20% higher stocking in thinning. Maintenance of 20% lower stocking in thinning increased, in general, the amount of harvested timber, but it could not compensate for the decrease of harvested timber due to increase of conservation area. Climate warming greatly increased all of the studied variables in northern Finland but decreased them in southern Finland, the most under the strongest climate warming scenario, RCP8.5. Climate warming also increased the quantity of deadwood throughout Finland. To conclude, we found clear trade-offs for production of different ecosystem services.
