Natural plant revegetation on reclaimed coal mine landscapes in Agacli-Istanbul

In this study, natural vegetation development was compared on one abandoned open coal mine spoil and three reclaimed coal mine areas with umbrella pine-Pinus pinea L., maritime pine-Pinus pinaster Ait. and leguminous black locust-Robinia pseudoacacia L. in Agacli-Istanbul. Soil data of these sample areas were determined in previous studies. These properties demonstrate physically and nutritionally poor conditions and some rehabilitative effects after tree species were introduced. The plant species composition and total coverage for each species (vertical projection onto the ground) was estimated visually and recorded on each sample plot. Naturally revegetated plant species, species composition, Shannon-Wiener diversity index values, species richness, evenness, total abundance and their cover-abundance scales were evaluated by comparing each other. Generally, the best-represented species belong to Rosaceae in all investigated plots. Shannon diversity index and its components give the different results among sample plots. However, higher values were found on reclaimed sites. Highest Shannon diversity index (H') was found on the sample area reclaimed with maritime pine. Plant species richness (S) was highest under umbrella pine and plant species evenness (J') was highest on black locust sample plot. Despite the sample area reclaimed, black locust has the more fertile soil conditions, it has only the highest plant species evenness (J') value among areas

Survived herbaceous plant species on compacted skid road in a fir (Abies bornmulleriana Mattf.) forest - A note

This study examines the plant species of herbaceous cover on a skid road subjected to soil compaction due to timber skidding in a pure fir (Abies bornmulleriana Mattf.) plantation forest. Previous studies have shown that ground based skidding damages soils, and degrades the ecosystem because it limits the recovery and growth of plant cover. However, some plant species can recover and survive after extreme degradation due to skidding. The composition of these species and their cover-abundance scales are examined. Sixteen species are determined belonging to 11 plant families. (c) 2008 Elsevier Ltd. All rights reserved

Revegetated herbaceous plant species on a compacted skid road

This study intended to determine the plant species on a skid road subjected to soil compaction due to timber skidding in a pure sessile oak (Quercuspetrea L.) forest. Our previous studies show that ground based skidding destroyed tile soil and ecosystem. The timber skidding limits recovery and growth of plant cover on skid roads. However, some herbaceous plant species show healthy habitat, and they can revegetate and survive after the extreme degradation in study area

Plant Species Recovery on a Compacted Skid Road

This study was executed to determine the plant species of herbaceous cover in a skid road subjected to soil compaction due to timber skidding in a beech (Fagus orientalis Lipsky.) stand. Our previous studies have shown that ground based timber skidding destroys the soils extremely, and degradations on ecosystem because of the timber skidding limit recovery and growth of plant cover on skid roads. However, some plant species show healthy habitat, recovery and they can survive after the extreme degradation in study area. We evaluated composition of these plant species and their cover-abundance scales in 100 m x 3 m transect. 15 plant species were determined belongs to 12 plant families and Liliaceae was the highest representative plant family. Smilax aspera L., Epimedium pubigerum (DC.) Moren et Decaisne, Carex distachya Desf. var. distachya Desf., Pteridium aquilinum (L.) Kuhn., Trachystemon orientalis (L.) G. Don, Hedera helix L. have the highest coverabundance scale overall of determined species on compacted skid road

Does Plant Knowledge within Urban Forests and Parks Directly Influence Visitor Pro-Environmental Behaviors

Urban parks and forests provide many services to society and are becoming essential components within urban landscapes worldwide. While substantial research and actions have been taken to understand various ecosystem services of urban forests and parks, significantly less effort has been made on people’s perceptions toward the effectiveness of these services. In addressing the above research needs, we conducted a field survey and hypothesized that an individual’s knowledge will lead to different pro-environmental behaviors in urban forests and parks. Using the Toledo, Ohio, USA as our study site, we collected 267 interviews from five of the area’s most frequented urban parks. A three-way ANOVA and two Partial Least Square Structural Equation Models quantified the causal relationship among demography, plant knowledge, environmental knowledge, and pro-environmental behaviors. We found that: (1) different levels of plant knowledge will have different influences on environmental behaviors; (2) pro-environmental behavioral models can be based on planned behaviors or habitual behaviors; and that (3) gender may not be an influential factor in determining pro-environmental behaviors. Environmental knowledge, especially plant knowledge, plays a key role in fostering pro-environmental behaviors. Therefore, we reason that disseminating plant knowledge education materials will profoundly raise visitors’ pro-environmental behaviors
