Climate change impacts biodiversity in a myriad of ways.  Some species may even flourish under climatic conditions which are more favourable as a result of climate change.  However, the rate of warming predicted is greater than anything which has been experienced for millions of years. Consequently there is a strong possibility that many species will find the physiological stress associated with temperature and precipitation changes too great, making it impossible for them to  adapt (Pimm 2009).  Whilst some changes will occur indirectly, as the result of climatic impacts on key ecological processes, including the frequency and intensity of fire events, predator-prey interactions, water flow, and nutrient cycling.  Anthropogenic stresses such as habitat loss and fragmentation, as well as the introduction of any invasive species which they may interact with, might exacerbate the impacts of climate change.

For biodiversity conservation to be effective in the long-term, it is critical that practices address new climatic conditions and that efforts to reduce non-climatic stresses continue. This will  support species, and the ecological processes upon which they depend on in order to adapt. With this aim in mind, there are several aspects to be considered, including:-

  • the protection and restoration of ecological and evolutionary connectivity
  • reducing other stresses (feral populations, pollution, habitat loss etc.)
  • increasing the size and number of protected areas
  • managing the matrices between protected areas
  • pro-actively protecting large, intact landscapes and seascapes

(Heller and Zavaleta 2009; Mackey et al. 2010; Watson et al. 2010).

The impacts of climate change can vary at a regional and even local scale (Trivedi et al. 2008), so in identifying relevant adaptation strategies, detailed climate change predictions specific to areas of conservation importance, and the likely responses of species are needed. Several tools are now available to facilitate this process.

Tools which can provide fine-scale predictions of climate change impacts include Climate Wizard from The Nature Conservancy. Details of this and others are given below. Predictions at a regional scale are available from the IPCC (Christensen et al., 2007) as well as World Clim (Chapter 4). 

In addition to fine-scale climate change predictions, it is important to have good information on the species and the ecological functions present in the area, to assess the vulnerability of its biodiversity. The IUCN is producing tools to guide vulnerability assessments of a range of species; helpful for identifying how they might be affected by climate change (see below).

Integrating climate change adaptation plans into more general conservation planning is still in its infancy, however a number of tools have been developed recently to support this process (Groves et al. 2010).

The tools typically follow the framework below:

  1. The identification of  biological features targeted for conservation (species, ecological processes, ecosystems) and gather explicit, measurable, management objectives for each;
  2. The building of a conceptual model to illustrate the climatic, ecological, social/economic drivers affecting each feature; examine how the feature and its drivers may be affected by multiple plausible climate change scenarios;
  3. Identifying intervention points and potential actions to achieve objectives for each feature under each scenario;
  4. Evaluating feasibility of, and trade-offs among, potential actions;
  5. Developing and implement an action plan;
  6. Evaluating the achievement of objectives, any issues which may have arisen and the corrective actions needed..

It is envisaged that the action plan will include:

The identification and  strengthening of key protected areas that are resilient to climate change; identifying bottlenecks; managing protected area networks to enhance landscape permeability for migratory, nomadic or wide-ranging species as well for the species with shifting ranges and to encourage a more environmentally sympathetic management of the landscape in general.

Species relocation, assisted migration, captive breeding, and germplasmstorage can all play a significant role in conservation activities. However, such measures are often expensive, less effective than in situ actions, only feasible on small scales and will rarely maintain vital ecosystem functions and services.

To reduce the negative impact of climate change on biodiversity we recommend:

  • Encouraging a move away from static targets for biodiversity conservation
  • Ensuring climate change adaptation activities are integrated across as many sectors/ministries as possible, whilst avoiding conflicting targets
  • Incorporating climate change predictions and vulnerability assessments into national and local Protected Area policy and land-use  management policies
  • Creating natural resource policies that address the interconnected impacts of climate change across separate ministries such as forestry, water, fisheries and wildlife. Incorporating adaptation into National Biodiversity Strategies and Action Plans (NBSAPs), to ensure that vulnerable ecosystems are addressed in National Adaptation Programmes of Action (NAPAs) and National Adaptation Plans (NAPs) and that these plans are integrated into other policies
  • Ensuring that any impacts are understood in terms of ecosystem services losses so that they can be incorporated into National Poverty Reduction Strategies

Case Studies

Coral Reef Conservation in the Face of Climate Change

Coral ecosystems are particularly vulnerable to climate change impacts. These rich marine ecosystems are important not just for biodiversity but also for the many people who depend upon them economically and socially. , This article sets out a framework for identifying and investigating strategies for responding to climate change whilst minimising risks to reefs and safeguarding local stakeholders’ livelihoods using examples from the Western Indian Ocean. By considering both environmental susceptibility and social adaptive capacity, responses tailored to local conditions can be achieved. (McClanahan et al. 2008).

Key Questions:

  1. How do the actions and policies needed to protect biodiversity in the face of climate change vary from those used to address other types of threat?
  2. How do you prioritise actions and policies for conserving biodiversity in the face of climate change when there are many dimensions of biodiversity and these may respond differently to change?
  3. How can policies and management plans be integrated to minimise the negative impacts of climate change on biodiversity and ecosystem services?
