Climate Change: SEAFWA Thoughts?

Ken Haddad, Executive DirectorFlorida Fish and Wildlife Conservation CommissionSeptember 2007

Southeast Director Responses

• Is your agency working on the issue? Most no but monitoring efforts will aid.

• Is your state government taking steps? Exec Orders, fuel alternatives

• Director ranking?…low to medium• Major Issues: Sea level, weather

extremes, migrations, range expansion of southern species, habitat change, exotics expansion, conversion of forest to fuel.

Goal: minimize species loss and optimize wildlife value and survival in the face of climate change

• Need to:– Generate information on the direction and

range of climate effects – ID highest value wildlife species and habitat

targets – Policy frameworks that are flexible to

uncertainties– Plan to mitigate adverse effects– Elicit political, economic and public opinion

that allows these responses.

Impacts and Vulnerability Earlier “greening” of vegetation linked to longer

thermal growing seasons Shifts in ranges and composition of algal and

plankton populations Range changes of wildlife populations and

vegetation Alterations in disturbance regimes of forests due

to fires and pests

Impacts and Vulnerability Combination of sea-level rise and human impacts

contribute to loss of coastal wetlands and mangroves; increased damage from coastal erosion and flooding

Corals vulnerable to thermal stress; have slow adaptive capacity

Altered spatial distribution of some infectious disease vectors

Impacts and Vulnerability Threats to freshwater resources critical to fish

and wildlife Increased invasion/spread of non-native species Changes in rainfall patterns- erosion, plant

communities, quality/quantity of surface and groundwater

Wetland migration or loss Shift in waterfowl nesting and migration

patterns

Impacts and Vulnerability

Salt marshes and mangroves losses where constrained by development or sediment deficits

High elevation habitats have no where to go coldwater fisheries and warming streams and

lakes

Short Term Solutions Convert marginal agricultural land into

forested land to increase carbon sequestration

Explore long-term impact of crop production for ethanol on

wildlife Conserve woodlands from

development

Longer Term Solutions (Adaptation)

Most stringent efforts cannot avoid further impacts in next few decades- makes adaptation more important

Need mix of mitigation, adaptation, technical development and research to combine with incentive-based policies and actions at all levels from individual to international

Adaptation measures in land-use planning & infrastructure design

Increase ability to predict biological responses

Data Gaps Lack of geographic balance in data and

literature on observed changes No clear picture of limits to adaptation

(highly dependent on species, and geographical factors as well as public opinion, political and financial constraints)

Landscape or Habitat-based Focus

• Large areas needed to allow diversity.• Areas of significant north-south • extentCorridors that connect affected areas• Areas inland of predicted flood zones• Migrant transit locations

Species Focus• Species with limited distribution• Species with limited movement/migration

capacity• Species with known narrow temperature

dependencies• Species isolated in discontinuous habitats• Highly charismatic and popular species• Species of high economic value

What are we doing now?

Long term monitoring of some species Planning process include restoration strategies

with a wider range of weather conditions Defining flows for streams, rivers and estuaries Starting the discussions

What are we doing now?

Monitoring of nonnative species Development of predictive models Benchmarking to evaluate future climate

variability Legislation/executive orders beginning to

generate action

What now? Many species and habitats will adapt without intervention Focus on species that will be challenged by

climate change Focus on species whose loss in the southeast

would be a significant or complete loss of the species in the world.

Focus on the distribution of habitats that species need

The climate change issue is larger than fish and wildlife

Maximize our influence across the whole range of climate change responses

Carefully consider and balance the modification of fish and wildlife regulations to reduce human costs of adaptation to climate change

Communicate the importance of our vision for active management of wildlife in response to climate change

Actively communicate policy objectives and constraints to public, media and legislature
