Abstract:

Abstract Curlleaf mountain mahogany (Cercocarpus ledifolius Nutt.) is a little-studied woodland tree that occurs in pure stands throughout the Intermountain West. Stand development and population dynamics of this species are poorly understood, despite their relevance to management. We describe here the development of stand age structures and population dynamics of mahogany woodlands in northern Utah using tree ages and measurements representing five structurally diverse stands. Establishment periods in all stands lasted decades, and regeneration continued intermittently in the absence of stand

Many Mahogany (Swietenia macrophylla King.) is used as the main tree in the area or the forestry industry plans. If the tree is planted monoculture, the mahogany stand has become highly vulnerable to pest and diseases, because monoculture tree plantations are an abundant food source for both organisms. This study aims to determine the types of fungi that attacking and cause disease in plant parts mahogany. The result showed that there are ten species of fungi that attack mahogany. Seven of them have been identified while the other cannot be identified. Fungi are attacked or negative associatio

For the younger generation to understand the practice of agroforestry from an early age, it is necessary to introduce it so that they are motivated to practice it as part of the family income. There are 4 forms of agroforestry, namely trees planted regularly with non-tree plants, there are 2 compositions, namely sengon trees with kimpul, Japanese papaya, sissy. Trees were planted around the land and non-tree trees, such as mahogany, cassava, sweet potato, chili, papaya

There are over 8,000 globally threatened tree species. For each species, there is a different story behind why they are threatened and what values we stand to lose if we do not find the means to save them. Mahogany, a member of Meliaceae, is a small genus with six species. Its straight, fine and even grain, consistency in density and hardness makes it a high valued wood for construction purposes. The bitter bark is widely used in traditional medicine in Africa. The high demand for bark has also led to the total stripping of some trees, complete felling of larger trees to get the bark from the

This study aims to determine acquire data on the species composition and structure of trees, as well as to analyze the health of trees growing in the Pematangsiantar Animal Park. Using the census approach, data collection was conducted. The health state of trees was determined using the Forest Health Monitoring (FHM) method, which measures tree health by categorizing the kind and severity of damage per every plant. Two indicators are utilized to measure tree health: tree damage and tree crown condition. The method of data collection was conducted on trees with a minimum diameter of 20 centimet

Comparation of Interception Loss on Mahoni (Swietania mahagoni) and Pinus (Casuarina cunninghamia)ABSTRACT. Interception of rain is the retention of rainwater on surface vegetation before it evaporates back into the atmosphere. Research relating to the interception is still lacking, so it is necessary to study the interception on some types of plants. Although the interception had a little value, and sometimes overlooked, but in some plants have a considerable effect. The purpose of this study was to determine the magnitude of interception in Mahogany and Pine trees, as well as to determine th

African Mahogany (Khaya senegalensis) is an important tree in Africa. A deciduous tree, reaching up to 35m in height on fertile soils. It has a diameter of up to 1.5 m with 8-16 m bole. The bark is dark grey or pink with red latex. The plant is commonly found in all the Northern States and around South Western States of Nigeria in the rain forest zone. The plant begins to produce fruit after 15 – 25 years throughout the dry season. The fruit is woody capsule, 4-10 cm long and dehisces at maturity. The seeds have a very low moisture content which is good for oil extraction hence its selection.
