To monitor the development of four community-managed forests, networks of permanent sample plots were established in 2005 at sites in Chitwan, Kaski and Mustang Districts, Nepal. This research note documents the procedures used when preparing for establishment of the plot networks, evaluates the applied stratification of the forest on the basis of data gathered in pilot surveys conducted in the early 2005, and provides a discussion on the implications of the choices made. Key words: Community-managed forests; permanent sample plots; stratification; allocation; estimates Banko Janakari Vol.16(2) 2006 pp.3-11

Canada's oldest forest research plot was laid out at Petawawa in 1918. Since then, hundreds of researchers have established plots, gathered data, and published results utilizing the Petawawa Research Forest. Many of the projects and plots were designed as long-term studies meant to endure and be re-measured over the decades. Although control plots were utilized, these early experiments were established prior to the benefits of repetition and experimental design. Later experiments were installed with three or more reps and factorial designs strengthening their analytical capabilities. Research priorities have shifted over time from documenting the results of a particular silvicultural treatment to understanding why silvicultural responses are obtained. Factors that influenced the continuance of some studies and the discarding of others are reviewed.Some studies achieved their original goals and have been continued for longer periods or utilized for additional goals. Characteristics such as tenure, experimental design, and site characteristics are described for several of these studies. Key words: long-term research, permanent sample plots, Petawawa

This research attempts to identify the existing condition of the community managed forest based on the assumption that it will serve as a proxy for the condition of other forests in the mid hills region of Nepal. The research area has an atypical variation in altitude and diverse pattern of vegetation. This study mainly focuses on estimating carbon content in the forest and identifying the species that has more carbon storage capacity. The research signifies the role of forests in mitigation of ‘Global warming’ and ‘Climate change’ by storing carbon in tree biomass. These types of community based forest management programs are significant for their additional carbon sequestration through the avoidance of deforestation and degradation. The carbon sequestration have a significant contribution to environmental benefits, any shrinkage of forests have an enormous impact on CO2 emission with long term consequences. Thus, the development and expansion of community managed forests provide many benefits to the adjacent community and globally at large.DOI: http://dx.doi.org/10.3126/njst.v12i0.6490 Nepal Journal of Science and Technology 12 (2011) 127-32

Resumen: En noviembre de 2006 se utilizó un prototipo de cámara de video, en la reserva privada El Zapotal, en la porción noreste de la Península de Yucatán, y obtuvimos la filmación de una pareja de jaguares en actitud de apareamiento. Esta filmación representa una de las primeras experiencias de su tipo, y ha proporcionado información única sobre comportamiento y fecha de apareamiento de jaguares libres, que es consistente con algunos resultados de investigaciones de amplio espectro y largo plazo sobre poblaciones de esta especie en Sudamérica. Palabras clave: Apareamiento, Panthera onca, videofilmación, Yucatán Abstract: In november 2006, using a prototype of video camera, we obtained the shooting of a pair of jaguars in mating attitude. This was done in the El Zapotal private reserve, in the northeastern portion of the Yucatan Peninsula, and represents one of the first experiences of its type, also providing unique information about the mating behavior and the date of occurrence. The latter is consistent with some results derived from wide spectrum, long term studies about jaguar populations in South America. Key words: Mating, Panthera onca, videoshooting, Yucatan

The study assessed the quality of stream water of the watershed within the Community-Based Forest Management (CBFM) Project in Cienda, Gabas, Baybay, Leyte, Philippines. Results showed that, on the average, streamflow velocity was 0.30m/sec, streamflow volume 0.32m3/sec, turbidity 2.96 ntu and the associated sediments 16.0 mg/ L. Odor and taste were unobjectionable. pH ranged from 7.50 to 7.0 while total hardness from 7.84 to 15.16 mg/L. The average nitrite (NO2) content was 11.115mg/L while nitrate (NO3) was 1.05 mg/L. The concentration of nutrients was also very low. Phosphorous (P) ranged only from 2.20 to 4.46 mg/kg or parts per million (ppm) while potassium (K) ranged from 3.71 to 3.90 ppm. Sodium (Na), calcium (Ca), and magnesium (Mg) concentrations were also very low. Heavy metals were detected but also at low concentrations.

Trembling aspen regeneration was studied in 2 types of partial harvest systems designed to harvest mature aspen but protect immature spruce and encourage natural aspen regeneration. Two partial harvest systems, where the residual aspen was either left in strips or was dispersed uniformly, were compared to traditional clearcuts. After the first and second year since harvest, aspen sucker density and growth was similar between the 2 partial harvests, but was much lower than in the clearcuts. However, in the partial cuts the regeneration density was very much dependent on the location relative to residual trees. The density of regeneration was inversely related to the basal area of residual aspen; however, sucker height was inversely related to the basal area of the residual spruce. Although there were adequate numbers of suckers after partial harvest, their viability and contribution to the long-term productivity of these mixedwood stands is not clear.

Long-term studies of the dynamics of managed forests in tropical regions are lacking. This study aimed to evaluate the dynamics of a tropical forest, over a 25-year period, that was experimentally logged in 1987 and 1988 and submitted to three different cutting intensities. All trees with diameter at breast height (DBH) ≥ 10 cm have been measured annually since 1990. The three logging intensities that were applied were: light (T1)-trees harvested with DBH ≥ 55 cm; medium (T2)-DBH ≥ 50 cm; and heavy (T3)-DBH ≥ 40 cm. Control plots (T0) were also monitored. The highest mean annual mortality rates (1.82% ± 0.38), recruitment rates (2.93% ± 0.77) and diameter increments (0.30 ± 0.02 cm) occurred in the T3 treatment. Shifts in dynamics of the forest were mainly caused by a striking increase in a fast-growing pioneer species and their high mortality rates. The loss in stocking caused by mortality was greater than to that of replacement by recruitment. The results demonstrated that selective logging altered the natural dynamics of the forest through increased: mortality rates, recruitment and growth rates of the residual trees.

Community-based forest management practices vary according to biophysical and management factors. This study aimed to explain the vegetation conditions of community-based forest management in Aik Bual and Setiling village, Lombok Tengah. The study site was divided into protected forest areas (HL) in Aik Bual Village with a legal community forest permit (Aik Bual-HKm), HL in Setiling Village with no legal community forest permit (Setiling-Non Permit), and HL in Aik Bual Village with no legal community forest permit (Aik Bual-Non Permit). Field measurement was conducted in July 2018 by establishing 12 plots of 20 m x 20 m. Each plot consisted of subplots of 10 m x 10 m, 5 m x 5 m, and 2 m x 2 m to collect data of woody and non-woody plants with the criteria of diameter (D) as follows: D ≥ 20 cm, 10 cm ≤ D < 20 cm, 2 cm ≤ D <10 cm, and D < 2 cm with tree height of < 1,5 m, respectively. The results showed that Aik Bual-HKm, Setiling-Non Permit and Aik Bual-Non Permit had 24, 13 and 22 species, respectively. Dominant species of vegetation at D ≥ 20 cm were Erythrina variegata and Swietenia macrophylla, at 10 cm ≤ D < 20 cm were Musa paradisiaca and Durio zibethinus, at 2 cm ≤ D < 10 cm was Coffea canephora, and at D < 2 cm were C. canephora and S. macrophylla. Vegetation diversity index (H') of plants at D ≥ 2 cm in Aik Bual-HKm was slightly higher (H'=1,78) than that in Setiling-Non Permit (H’=1,04) and Aik Bual-Non Permit (H’=1,15), although these are classified as moderate. The results illustrated the possible differences of vegetation diversity in community-managed forests with and without legal permission.Keywords: agroforestry, land tenure, protected forest, vegetation analysis
