“…Mean annual temperature is 29.5°C and the mean annual precipitation is 1250 mm. Prosopis is the single most dominant invasive species in Point Calimere, where it colonised vast grassland habitats critical for the survival of unique wildlife (Baskaran et al, 2016). Prosopis plants range from 30 to 50 years of age based on a cumulative girth size (cumulative circumference at 1.3 m height) of 3 m. The State Forest Department of Tamil Nadu has started to remove 15 ha of Prosopis at Point Calimere in May 2015 as a part of the "Biodiversity and Greening Project.…”

“…A loss of forest area and local species diversity, including plant and wild animals, was observed in Point Calimere in 1940s as consequence of an experiment designed to grow Prosopis for wood and tannin production (Ali, 2005). Studies based on LANDSAT ETM images showed that the invasion of Prosopis led to a reduction in open grasslands (Baskaran et al, 2016). The loss of open grasslands is a major threat especially to the endangered blackbuck (Antelope cervicapra) in Point Calimere (Ali 2005;Baskaran et al, 2016).…”

Invasion of alien plant species can alter local plant diversity and ecosystem processes closely linked to soil organic carbon (SOC) and nutrient dynamics. Soil ecosystem processes such as microbial respiration and enzyme activity have been poorly explored under alien plant invasion and especially following invasive plant species removal. We studied the impact of Prosopis juliflora and Acacia mearnsii invasion and subsequent removal on local plant community composition and diversity and on soil microbial respiration and enzyme activity in two biodiversity hotspots in Southern India. Removal of Prosopis promoted recolonisation of local vegetation as indicated by a 38% and 28% increase in species richness and ground vegetation cover, respectively, compared to an unremoved site. Prosopis and Acacia removal led to a significant reduction in soil microbial biomass C (MBC), respiration, dehydrogenase and urease activity due to increased microbial respiration and N mineralisation rate. Higher metabolic quotients qCO 2 in soil at Prosopis and Acacia removed sites indicate that MBC pools declined at a faster rate than SOC, resulting decreased MBC/SOC ratios compared to their respective removed sites. Natural and undisturbed ecosystems maintain more SOC through increased belowground and aboveground C input in the soil, resulting in a higher MBC content per unit SOC. Our results indicate that the interaction between above-and below-ground communities is a critical factor determining the structure and dynamics of local plant communities, especially in ecosystems affected by plant invasions.

We assess the impacts of human paths, trails, and roads on plant species richness and Shannon diversity. Most reviews of this topic have not considered community‐level measures and have focused on excessive tourism impacts. We found significant positive effects of paths on plant richness and diversity. The effect size for richness was highest when studies included roads (paved) or trails (unpaved). The effect size found for diversity was highest when studies were in grasslands. We also found experimental designs comparing high levels of path use to low levels of path use, near‐to‐path versus far‐from‐path and path‐presence versus path‐absence comparisons obtained the largest effect sizes. There was no evidence that non‐native species explained most increases in species richness or diversity. The effect sizes of human paths on plant communities are comparable in magnitude to those reported for other mammals’ disturbance and ecosystem engineering activities.

“…Salah satu faktor yang diduga menjadi penyebab menurunnya kuantitas dan kualitas habitat adalah penggembalaan ternak yang memasuki habitat rusa timor (Sawadogo et al 2005;Yoshihara et al 2008;Baskaran et al 2016). Penggembalaan ternak di dalam hutan merupakan fenomena umum masyarakat pedesaan sekitar hutan di daerah tropis.…”
