As aquatic plants in Choghakhor wetland were fully grown, homogeneity or heterogeneity of vegetation units and their zones were measured based on quantitative characteristics of plants communities. Vegetation sites were evaluated from shore to water body by linear transects and sampled quantitative characteristics in 1 × 1 m quadrates at 10 and 20 m intervals. Frequency Presence Diagram was used in order to recognizing of zoning and horizontal array of wetland plants. Summing of species array based on water depth and dominated planttypes were shown that wetland vegetation cover is distinguished to two main zones and one transitional zone.

Transition to other LULC types is one of the major challenges of Iran's Hyrcanian forests in Golestan province. To consider how LULC change scenarios affect GHGs, REDD project was executed in a period of 30 years (2018–2048) at intervals of 5 years. In this regard, study area was divided into the project area and leakage belt based on the Multi Criteria Evaluation (MCE) derived forest suitability map. In the baseline scenario, it was assumed that the trend of past LULC changes will continue. Results By implementation of the project scenario, some degradation activities were controlled. Project scenario was executed with different project success rates (PSR) of 90...
