Evaluating The Success Of Seed Sowing In A New England Grassland, Chad C. Jones, Glenn D. Dreyer, Nels Barrett Jan 2013

Evaluating The Success Of Seed Sowing In A New England Grassland, Chad C. Jones, Glenn D. Dreyer, Nels Barrett

Botany Faculty Publications

Grassland habitat is declining in the northeastern United States, leading to a decline in associated native species. Consequently, there is considerable interest by land managers in conserving and restoring grassland habitats in the Northeast. However, unlike the Great Plains and Europe, quantitative monitoring of restoration sites is uncommon, making it difficult to improve new restoration projects. Here we evaluate a grassland restoration in Waterford, Connecticut to determine if mechanical clearing of woody vegetation combined with sowing 23 native grasses and forbs led to successful establishment of these species. We also compared cover, diversity, and colonization by exotic and woody species …


Challenges In Predicting The Future Distributions Of Invasive Plant Species, Chad C. Jones Nov 2012

Challenges In Predicting The Future Distributions Of Invasive Plant Species, Chad C. Jones

Botany Faculty Publications

Species distribution models (SDMs) are increasingly used to predict distributions of invasive species. If successful, these models can help managers target limited resources for monitoring and controlling invasive species to areas of high invasion risk. Model accuracy is usually determined using current species distributions, but because invasive species are not at equilibrium with the environment, high current accuracy may not indicate high future accuracy. I used 1982 species distribution data from Bolleswood Natural Area, Connecticut, USA, to create SDMs for two forest invaders, Celastrus orbiculatus and Rosa multiflora. I then used more recent data, from 1992 and 2002, as validation …


Current And Potential Distributions Of Three Non-Native Invasive Plants In The Contiguous Usa, Chad C. Jones, Sarah Reichard Jan 2009

Current And Potential Distributions Of Three Non-Native Invasive Plants In The Contiguous Usa, Chad C. Jones, Sarah Reichard

Botany Faculty Publications

Biological invasions pose a serious threat to biodiversity, but monitoring for invasive species is time consuming and costly. Understanding where species have the potential to invade enables land managers to focus monitoring efforts. In this paper, we compared two simple types of models to predict the potential distributions of three non-native invasive plants (Geranium robertianum, Hedera spp., and Ilex aquifolium) in the contiguous USA. We developed models based on the climatic requirements of the species as reported in the literature (literature-based) and simple climate envelope models based on the climate where the species already occur (observation-based). We then compared the …


Plant Succession On Gopher Mounds In Western Cascade Meadows: Consequences For Species Diversity And Heterogeneity, Chad C. Jones, Charles B. Halpern, Jessica Niederer Jan 2008

Plant Succession On Gopher Mounds In Western Cascade Meadows: Consequences For Species Diversity And Heterogeneity, Chad C. Jones, Charles B. Halpern, Jessica Niederer

Pocket gophers have the potential to alter the dynamics of grasslands by creating mounds that bury existing vegetation and locally reset succession. Gopher mounds may provide safe sites for less competitive species, potentially increasing both species diversity and vegetation heterogeneity (spatial variation in species composition). We compared species composition, diversity and heterogeneity among gopher mounds of different ages in three montane meadows in the Cascade Range of Oregon. Cover of graminoids and forbs increased with mound age, as did species richness. Contrary to many studies, we found no evidence that mounds provided safe sites for early successional species, despite their …
