Goal Fifteen: Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss

The San Diego region enjoys a high quality of life, although challenges still remain. SANDAG's 2021 Regional Plan seeks to improve the way we all move throughout the region while seeking to ensure that we can all lead healthy lives. 
Goal 15 Life on land

Target 15.1

By 2030, ensure the conservation, restoration, and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains, and drylands, in line with obligations under national, state, and regional guidelines.
Indicator 15.1.1:
Forest area as a proportion of total land area.
Indicator 15.1.2:
Proportion of important sites for terrestrial and freshwater biodiversity that are covered by protected areas, by ecosystem type.

Target 15.3

By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought, and floods, and strive to achieve a land degradation-neutral region.
Indicator 15.3.1:
Proportion of land that is degraded over total land area.


Target 15.4

By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, to enhance their capacity to provide benefits that are essential for sustainable development.
Indicator 15.4.1:
Coverage of protected areas of important sites for mountain biodiversity.

Target 15.5

Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity, and by 2030, protect and prevent the extinction of threatened species.
Indicator 15.5.1:
Red list index.


Target 15.8

By 2030, introduce measures to prevent the introduction and significantly reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species.
Indicator 15.8.1:
Proportion of member agencies adopting relevant legislation and adequately resourcing the prevention or control of invasive alien species.


Target 15.9

By 2030, integrate ecosystem and biodiversity values into regional and local planning, development processes, and poverty reduction strategies and accounts.
Indicator 15.9.1:
(a) Number of local agencies that have established local targets in accordance with or similar to Aichi Biodiversity Target 2 of the Strategic Plan for Biodiversity 2011–2020 in their local biodiversity strategy and action plans and the progress reported toward these targets; and (b) integration of biodiversity into regional accounting and reporting systems, defined as implementation of the System of Environmental-Economic Accounting.


Target 15.A

Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems.
Indicator 15.A.1:
Public expenditure on conservation and sustainable use of biodiversity and ecosystems.
