How will plant species respond to changing situations in the future?

How do different land management decisions impact on the future distribution and status of plant species?

To find the answers to these questions, we simulate the responses of different plant species to changes in their environment.

How do UK peatlands respond to climate change?

This project aims to predict the responses of plant species in UK peatlands, particularly bryophytes, to climate change. 

UK peatlands are huge carbon stores made up of waterlogged soils full of dead or decaying plant matter. We identified peat bog areas in Scotland vulnerable to increased drying under future climate scenarios. The carbon emitted from drying peat bogs can be greater than the carbon captured by the trees that colonize them.

Informing peatland management 

We want to know how different land management decisions impact on the future distribution and status of peat bog plant species. This information will help manage competing land-use requirements by advising where it would be possible to increase woodland cover while maintaining the quality and extent of peatland. 

Our work also investigates the susceptibility of peat bogs to colonization by invasive species, such as birch, spruce and rhododendron. 

Working together 

We are collaborating with colleagues at the Universities of Glasgow and Edinburgh and with Peatland ACTION, a Scottish-based NGO working with Scottish Natural Heritage (SNH).

The importance of functional diversity for ecological stability

To demonstrate the importance of functional diversity for ecological stability, we will extract plant trait information from taxonomic literature for UK species. We will use this, along with non-taxonomic traits such as growth rates and dispersal distances, to capture species-level dynamics in growth, competition and dispersal between species and predict their occurrence now using additional soil cover and land-use data for the UK and in response to future changes in climate.

The aim is to determine the measurable threshold for net negative or positive biodiversity change that can be detected by various measures of biodiversity, in the presence of the stochastic noise inherent in any biological system.

We will use available distribution data for UK plant species to test predictions of their occurrence, and the impact of planned and expected land-use and climate change to guide future decision making. 

Plants Under Pressure projects

Supported by funding from the Natural Environment Research Council.

Plants Under Pressure

Assessing threats to plants and monitoring the state of the plant world.

Bryophytes (mosses, liverworts and hornworts)

We have assessed 1021 species of bryophytes from around the world using the IUCN Red List Criteria, a ten-fold increase.

Hotspots of plant diversity

Expeditions to areas of high plant diversity help us to ensure that our IUCN Red List assessments are accurate.

Comparing plant diversity indicators

Can we detect small-scale changes to biodiversity?

Pteridophytes (ferns, lycophytes and their allies)

We have tripled the number of species of pteridophytes assessed using the IUCN Red List Criteria.

Essential Biodiversity Variables

How should we study the full extent of change to biodiversity?
