Vegetation due to its root system by creating cohesion of soil particles, significantly affects hill slope mechanical properties related to shallow landslides and slope stability. In this regard, the root engineering characteristics of forest species are important. The aim of this study was to investigate the distribution pattern of persian oak and hawthorn in Zagross forests. For this purpose,...

     This study was investigated the gas exchange parameters and Chlorophyll fluorescence yield in Iranian oak (Quercus macranthera F & M) seedling under drought stress in Golestan Province. For this aims, 2 years old of Iranian oak exposed (Quercus macranthera F & M) seedling from Golestan province population exposed to three soil moisture regimes (control, any drought stress (95% field capaci...

We analyze interannual to multi-decadal growth variations of 555 oak trees from Central-West Germany. A network of 13 pedunculate oak (Quercus robur L.) and 33 sessile oak (Quercus petraea (Matt.) Liebl.) site chronologies is compared with gridded temperature, precipitation, cloud-cover, vapor pressure and drought (i.e., Palmer Drought Severity Index, PDSI) fluctuations. A hierarchic cluster an...

An individual tree basal area increment model was developed for blue oak (Quercus douglasii Hook. & Arn.) in California, an important woodland tree for wildlife habitat. Box-Cox regression based on 895 increment cores that showed current basal area and the relative size of the tree crown were significant variables. Models to link basal area changes over time with tree height and crown cover wer...

With the reemerging discussion of gentrification in the urban landscape, an exploratory case study of the Oak Park Redevelopment Plan in Sacramento, California, was conducted to better understand the community’s gentrifying characteristics and the implications once the redevelopment goals are met. In addition, a conceptual framework (CF) was formulated in order to examine the components and pro...

Proper protocol for mycorrhizal inoculation of container grown landscape trees is uncertain. Therefore, vegetative and commercial spore inoculum of Pisolithus tinctorius were applied to Quercus palustris (pin oak) and Q. coccinea (scarlet oak) seedlings. All plants were grown in containers filled with 0.9 liters of milled pine bark, sterilized milled pine bark, sterilized mineral soil, or steri...

Severe bark decay disease was observed on oak logs at a shiitake cultivation farm in Geochang-gun, Gyeongnam province. The symptoms observed were fruiting bodies that had developed on the top and side surface of oak logs. As a result, the bark came off easily exposing the sapwood. Slime mold specimens collected from oak logs showed developing fruiting bodies comprising of stalks, hypothallus, c...
