Tree Composition

This paper describes early results from a survey that was developed to allow rapid, yet reasonably accurate, estimates of street tree composition in Canadian communities. To carry out surveys, participants walk (or drive) a number of 0.5-km routes, identifying all trees within 10 m of the road edge. The number of survey routes in each community was determined such that tree densities could be estimated within reasonable error bounds: ±5 trees/km for common species and ±1 tree/km for uncommon species. Information from this initiative has already supported invasive species risk assessments and urban forest management activities.

Abstract Stumpage price is one of the key economic inputs in developing sustainable forest-management plans and analyzing forest-management decisions and investments. A robust method to forecast stumpage prices and prediction intervals would help timberland owners and consultants bound uncertainty and improve the chance that future management actions agree with specified objectives. We evaluated three forecasting methods: simple moving average, linear weighted moving average, and exponential weighted moving average. Real annual stumpage prices for New York’s six most common species were used to evaluate the robustness of the three forecasting methods. We concluded that, while being more complex computationally, the exponential weighted moving average was preferred to the simple and linear weighted moving average.

Recent shifts in emphasis to preservation of biological diversity and establishment of large nature reserves have resulted in downgrading of the perceived importance of data at the population level. These shifts in emphasis, while laudable, should not result in loss of focus on the fundamental importance of population information. Suitable habitat, although a prime necessity, is not sufficient for wildlife preservation. Species may not occupy otherwise suitable habitat because of internal (predation, interspecific competition, disease) or external (adverse climate, exploitation, disturbance, impact of exotic species, pollution and toxicants) factors. Historical impacts may persist for many years, and may require active restoration. Forest management plans must consider population data on a metapopulation scale. Data for common species can be at the reconnaissance level whereas for threatened or sensitive species they need to be more detailed. To evaluate sustainability, population data must be integrated with forest stand data in projection models to predict habitat-population mosaics at various times in the future. These models must be developed and improved over time in an adaptive management approach.

The Status

The natural conditions, climate change and socio-economic challenges related to the transformation from a socialistic society towards a market-driven system make the implementation of sustainable land management practices in Mongolia especially complicated. Forests play an important role in land management. In addition to providing resources and ecosystem functions, Mongolian forests protect against land degradation.We conducted a literature review of the status of forest management in Mongolia and lessons learned, with special consideration to halting deforestation and degradation. We grouped our review into seven challenges relevant to developing regionally adapted forest management systems that both safeguard forest health and consider socio-economic needs. In our review, we found that current forest management in Mongolia is not always sustainable, and that some practices lack scientific grounding. An overwhelming number of sources noticed a decrease in forest area and quality during the last decades, although afforestation initiatives are reported to have increased. We found that they have had, with few exceptions, only limited success. During our review, however, we found a number of case studies that presented or proposed promising approaches to (re-)establishing and managing forests. These studies are further supported by a body of literature that examines how forest administration, and local participation can be modified to better support sustainable forestry. Based on our review, we conclude that it is necessary to integrate capacity development and forest research into holistic initiatives. A special focus should be given to the linkages between vegetation cover and the hydrological regime.
