What is the Difference between Climate Change Resiliency and Adaptation?

Ecological resilience, as used here, is the natural adaptive capacity of systems to selforganize in response to change. Novel ecosystems via “new trajectories” may result. Adaptation as defined by the IPCC is the process of adjustment to actual or expected climate and its effects on the environment. In natural or human-made systems, human intervention may facilitate this adjustment. Fundamentally there are only two parts to adaptation science: • calculating the probability of a future event;

• creating contingency plans for events most likely to materialize, with the greatest vulnerabilities. (Nitschke and Innes 2008; Martin-Breen and Anderies 2012; IPCC 2014)

A Warm Time in the Past – The Mid-Pliocene: about 3.3 to 3.0 Mya Proxy for Future Climate Environment in Late 21st Century The Mid-Pliocene - mean global temperatures were substantially warmer for a sustained period (estimated by GCMs to be about 2°C to 3°C above pre-industrial temperatures; Chandler et al., 1994; Sloan et al., 1996; Haywood et al., 2000; Jiang et al., 2005), Under current pledges and commitments, the world could reach 4°C degree warming by the end of the century and 2°C warming as early as 2040 (IPCC Fifth Assessment, 2013).

Climate Change Impacts on Wetlands: Drought, Flooding, Warming Water, Soil Carbon Storage

Vulnerable Wetlands

Wetlands cover 6% of the world’s land surface and contain about 12% of the global carbon pool (IPCC 1996). Climate change will affect the hydrology of individual wetland ecosystems mostly through changes in precipitation and temperature regimes with great global variability. Wetlands that are most vulnerable to projected changes include:

depressional wetlands with small watersheds;

boreal peatlands, and bogs - dependent on the frequency and timing of precipitation and drying events, as well as duration of snow cover;

shallow or high groundwater wetlands such as forested, shrub and fresh meadow, seasonal or temporary wetlands;

coastal wetlands impacted by flooding and storm surges - One potential impact of global warming is the inundation of the Earth's low-lying coastal areas by rising sea level

Other anthropogenic Influences Interacting with precipitation and temperature impacts.

Plan for Change Vs. Business as Usual

Wetland adaptation activities should be described as measures taken to manage, conserve, and protect coastal and inland wetlands and their functions in order to support key services: • Water quantity management – flood storage, groundwater storage and recharge; • Water quality protection – filtering out pollutants as part of buffering against increased storm runoff and larger precipitation events; • Hazard management and flood abatement – shoreline stabilization, storm surge buffering;

• Habitat/wildlife protection – including sustaining habitat corridors and maintaining biodiversity, and • Carbon sequestration – reducing greenhouse gases and protecting wetland soils.

Vulnerable Coastal Wetlands

Coastal Wetlands =Those wetlands (tidal and fresh) within a HUC 8 watershed that are adjacent to and drain to the Atlantic, Pacific, or Gulf of Mexico, and also in the Great Lakes drainage. More than 50% of nation’s population are concentrated along coasts where wetland biodiversity is threatened by: • floods and droughts • surface water diversions • groundwater withdrawal • sea level rise and storm surges.

Managers Will Have to Deal With Novel Climate Change Challenges.

Considerations for Wetland Restoration in the Face of Climate Change •

Plan for a warmer climate, including temperature, drought, and hydrologic tolerances; develop applied research to determine plant tolerances.

Use native wetland plants found in wide range of latitude gradients, soil types, and hydrological conditions.

Create wetland corridors to facilitate native animal and plant migration (LCCs); reduce negative impacts of non-native wetland plants. Consider that southern species will migrate northward.

Use wide seed sources that provide enough genetic variation for resiliency to climate change.

Provide wetland buffer zones along coastal areas for flood protection.

Protect refugia for rare wetland species, where they occur; facilitated relocation may be necessary.

Conduct well-designed long-term monitoring of habitat, diseases, pests with management considerations.

Apply advancing satellite imagery and GIS for modeling past, current, and projected hydrology, wetland vegetation, soils, etc.
