Northeast Regional Plan

• Monitoring over 1985-2001: 7% losses • Threats : agriculture, urbanization, oil/gas development, highways/infrastructure, climate change, etc.


DRAFT MANAGEMENT GOALS AND OUTCOMES FOR WETLANDS

Northeast Regional Plan

Wetlands as well as their functions and ecosystem services are protected, restored, or enhanced Wetlands contribute to maintaining or improving surface water quality and other watershed management objectives

No further net loss of wetland area and functions Restore lost or degraded wetlands where feasible and beneficial For ecologically significant wetland complexes, maintain or restore associated upland areas for landscape connectivity Maintain core ecological functions and services of wetlands (e.g., water storage, flood control, biodiversity support, climate regulation, etc.)


DRAFT MANAGEMENT GOALS AND OUTCOMES FOR WETLANDS Wetlands are appreciated and valued by producers, industry, government, and the public Wetlands are conserved and managed by multiple stakeholders based on a land stewardship ethic

Knowledge of wetlands is improved

Knowledge of wetlands in the watershed is enhanced, including distribution, functions, and services of wetlands and interrelationships with surrounding areas and society

Northeast Regional Plan

Landowners, governments, and other stakeholders are active stewards of wetland environments

BASELINE SUMMARY OF ALL SITES ASSESSED IN THE RED DEER RIVER (1999-2010): - Healthy: 25% - Healthy, but with Problems: 49% - Unhealthy: 27%


Northeast Regional Plan

DRAFT MANAGEMENT GOALS / OUTCOMES FOR RIPARIAN AREAS Riparian ecosystems and associated Riparian areas and their related adjacent upland areas are kept intact functions and ecosystem and ecologically functional

services are protected or restored

No further net loss of riparian areas

Riparian areas contribute to maintaining or improving surface water quality and other watershed management objectives

Core ecological functions of healthy riparian lands are maintained (e.g., bank stability, water quality protection, water storage and flood mitigation, biodiversity, fish habitat support, etc.) Invasive plant species are reduced, particularly in riparian lands adjacent to watercourses and water bodies


Northeast Regional Plan

DRAFT MANAGEMENT GOALS / OUTCOMES FOR RIPARIAN AREAS Riparian areas are appreciated Landowners, governments, and other and valued by landowners, stakeholders are active stewards of riparian industry, and the public areas Riparian areas are conserved and managed by multiple stakeholders Knowledge of riparian areas is improved over Enhanced knowledge and understanding of: time - the distribution variable width riparian areas - functions and services of riparian areas - the importance of the composition, structure and health of upland areas adjacent to riparian areas

DRAFT MANAGEMENT GOALS AND OUTCOMES FOR LAND USE

Land uses are located and managed in ways that do not result in unacceptable impacts to water quality, water quantity and aquatic ecosystem health

Northeast Regional Plan

Planning, approval and management of land use and human activities in the watershed is aligned to achieve regional watershed management objectives

Public and private lands are managed with source water protection as a high priority Ecological infrastructure (including wetlands, riparian areas, alluvial aquifers, native vegetation, steep slopes) is conserved and integrated when planning and managing land uses Particular attention is paid to the headwaters and other highly sensitive areas when planning and managing land uses The RDRWA collaborates with provincial and municipal government agencies and other groups to facilitate efficient resourcing and delivery of watershed protection programs and services Cumulative effects management, risk mitigation, and integrated land management principles are applied to land management decisions Partnerships between individuals, community groups, businesses and government agencies are cultivated to achieve plan goals and objectives


DRAFT MANAGEMENT GOALS AND OUTCOMES FOR LAND USE Educational opportunities are provided to identify ways to contribute to a healthy watershed

Northeast Regional Plan

Knowledge of land uses and watershed functions increase over time

Watershed functions and ecological services are better understood by residents, governing agencies, First Nations and stakeholders Appropriate actions to maintain a healthy watershed environment are taken by individuals, municipalities, developers, industry, farms, etc. People recognize that a healthy economy depends on a healthy watershed Knowledge of how land uses impact the watershed is enhanced Enhanced knowledge and understanding of the key ecosystem services provided by ecological infrastructure in the watershed Knowledge of Beneficial Management Practices, resulting ecosystem response, and associated costs evolves

KEY MANAGEMENT RECOMMENDATIONS


Recommendations Monitoring, Research, BMPs The report recommends: • Priorities for monitoring / data acquisition • Research needs

Northeast Regional Plan

• Key Beneficial Management Practices (BMPs)


Land Use: General BMPs • Avoid Developing Ecological Infrastructure • Establish new Municipal or Provincial Parks • Compliance and Enforcement

Northeast Regional Plan

• Apply Integrated Land Management Principles • Erosion and Sediment Control Practices • Education strategies, including focus on economic / social benefits of ecological infrastructure • Regional plans / ALSA / market- based instruments, etc


Compensation Considerations • Wetlands have compensation program (riparian areas?) • Ensure compensation if impacts are unavoidable

Northeast Regional Plan

• New wetlands = function of the disturbed wetlands • Mitigation bank and market • Consider size, shape, riparian buffer, etc.


Specific BMPs: Urban / Rural Development • Reduce Sprawl

Northeast Regional Plan

• Limit rip rap, gabions, channelization, use bioengineering • Convert industrial / commercial uses in riparian areas to open spaces over time • Develop + enforce bylaws / plans with the watershed in mind • Recreation management: • indirect (signage, education) • direct (access control, siting /design, facilities, bylaws)


Specific BMPs: Agriculture • General: •Conservation Tillage •Rotational grazing, time controlled grazing, stocking rates •Highest degree of focus on more sensitive areas

Northeast Regional Plan

• Avoid / restore wetlands • Riparian: •Well vegetated riparian buffers •Convert annual crops to hay •Leave crop stubble in riparian areas, or use fall cereals •Restrict livestock access (fencing, cattle nose pump, etc.)


Other Land Uses

Northeast Regional Plan

• Country Residential •Septic Management / Sludge Management •Oil / Gas • Erosion / Sediment Control • Emergency response / readiness • Pipeline crossing studies • Reclaim disturbances as soon as possible • Conserve / restore riparian and wetland areas • Adequate water management •Forestry •Avoid riparian areas, steep slopes •Follow CSZ-Z809 Forest Certification Standards and all provincial regulations
