Individual tree growth models are important decision-making tools for forest management. We developed individual tree basal area growth models with Blue pine (Pinus wallichiana) data from Lete and Kunjo areas of Mustang district in Nepal. The sample trees were identified from all applicable ages, sizes, site qualities, and stand conditions and were cut. Diameters and ages were measured on the cut surface of stump (at 30 cm above ground). With the application of the auto-regressive error-structured modelling approach, we fitted Bertalanffy function to the data from 94 stumps by using basal area growth per year as dependent variable and stump age or stump diameter as independent variable. The age-independent individual tree basal area growth model showed better fits (R2 adj = 0.8324) than its agedependent counterpart (R2 adj = 0.8174). Because of having better fits and being easier for application, the ageindependent model is recommended for predicting basal area growth per year at an individual tree level for Blue pine across Lete and Kunjo areas of Mustang district. © 2012 Korean Forest Society.

Public plantations are managed under agro-forestry system which is aligned with the purpose of REDD+ reward but it needs sufficient records of carbon. Thus, objectives of the study were to compare the carbon stocks of public plantations with neighboring sites, show the variation in mean annual increment carbon (MAIC) and explore changes in soil C, N, P and K after plantation. Three public plantations of Mahottary, Nepal were selected for study. Altogether 28 sample plots were randomly established navigating GPS coordinates in the quadrates of 10mx10m for pole and 1mx1m for litter and grasses. Height and diameter of pole were measured and samples of others were also collected. The soil samples were collected from the centre of the plot from 0- 0.1m, 0.1-0.3m and 0.30-0.60m depths simultaneously. There were significant differences in carbon stocks with 140.32 t ha-1 in plantation and 68.39 t ha-1 in neighboring site of Shreepur public plantation. The highest value of MAIC was found nearly 10.19 t ha-1 while the values of soil C and N were 31.46 t ha-1 and 98.41kg ha-1 respectively in 0-0.1m and decreased by soil depths in Shreepur site. Same trend was found in soil P and K to all sites. © 2013 IJED.

Decentralised forest management is believed to hold potential for increased economic and social equity. Implications of the associated local forest law enforcement on livelihoods, however, are not well understood. This paper explores the impacts of local forest law enforcement with a focus on the poorest forest users in community-managed forests. A case study including 14 community forest groups in western Nepal was conducted in 2008. Methods included review of archival data, a stakeholder survey (n = 211), and recall of forest crimes by a random household sample (n = 252). Local forest law enforcement was found to detect far more crimes than district-level enforcement. Crimes are primarily small-scale unauthorised appropriation of products for subsistence use by poorer households and rules are lightly enforced. It is argued that local law enforcement, while apparently not economically harmful to the poorer in the short term, may be used to perpetuate existing wealth and cast-based social inequities. © 2011 Steve Harrison, John Herbohn.

Community forestry in Nepal is one of the most cited examples of participatory management of natural resources. However, such programs have not yet been able to fully ensure equitable, gender-sensitive, and poverty-focused outcomes. This study examines factors influencing participation of households in forest protection, resource utilization, and collective resource management decision-making activities. The study was conducted among five selected forest user groups in the Kaski District. The analysis is based on a household survey that included a random sample of 176 respondents (69 males and 107 females). Three ordered logit regression models were developed to examine determinants of household participation in forest protection, resource utilization, and decision-making activities. Analysis showed that larger sized households belonging to forest user groups that owned less land were more likely to participate in forest protection activities. Women from larger households located closer to forests and markets were more likely to participate in forest resource utilization activities. Households with more livestock belonging to forest user groups that managed forests in good condition were also more inclined to participate in resource utilization activities. Women and individuals from lower castes demonstrated lower levels of participation in decision-making processes. Low participation was associated with education level and traditional customs, which may result in low representation of some social groups in forest user group committees. © 2013 Elsevier B.V.

A survey was conducted to examine agrobiodiversity status of farms in the Pokhare Khola watershed of Dhading district in the Middle-Hills of Nepal. A total of 53 farmland tree and one crop species from 22 families were documented. The most commonly found species were fruit and fodder species (on over 60 % farms) including banana (Musa paradisiaca), khasrato (Ficus hispida) and khanayo (Ficus semicordata). Tree density was highest (226/ha) on marginal farms (farm area ≤0.25 ha) and lowest (165/ha) on small farms (farm area 0.26-0.5 ha). For the study area as a whole, the Shannon-Wiener species diversity index was 3.26 and the species evenness index 1.89. Large farms (farm area >1 ha) had the greatest tree species diversity (4.47 ± 0.52) and marginal farms the lowest (2.18 ± 0.37), indicating the positive relationship between farm size and species diversity. A total of six types of cereals and 18 types of vegetable crops were grown in the study area. The major livestock component of each household was chickens (average 8/household) and goats (6/household). The mean value of livestock in the large farm category was estimated as $2235, significantly higher than that of the other three categories. A significant relationship was found between agrobiodiversity and livelihoods, irrespective of annual production, and the critical role of the farmed landscape in agrobiodiversity conservation was apparent. © 2013 Steve Harrison, John Herbohn.
