Natural Resources, Climate Change, and Policy Workshop
- Tom Robinson, Director of Conservation, Science, and Innovation, Bay Area Open Space Council
- Carrie Schloss, Spatial Data Scientist, The Nature Conservancy
This presentation was given during a workshop at the Bay Area Greenprint Launch Event on June 21, 2017 at the David Brower Center in Berkeley, CA. More info on the Bay Area Open Space Council's blog: http://openspacecouncil.org/the-bay-area-greenprint-has-launched/
11. Amounts and proportions of flood-absorbing
land cover types
Estimate of sea level rise inundation at 2050
and 2100
500-year floodplain as a proxy for “extreme
weather events”
How much coastal and flood-prone “green
infrastructure” is there to attenuate flood waters
and destructive flood energy?
14. Benefits of Agriculture
• Bay Area residents “take pride in their region and its
unique quality of life, who are sympathetic with the
idea of preserving family farms, and many who have
embraced the idea of eating locally.”
–2011 American Farmland Trust report
• $2.36 Billion gross production in the Bay Area (Ag
Commissioners)
• 400,000 local jobs (2013 SPUR report)
• Ranchers and farmers steward the majority (~2.5M
acres) of our privately owned surrounding open spaces
• Lost 100 square miles (2 San Franciscos) of agricultural
land since 1984

is in my Area of Interest”
Only 9% of Prime Farmland is protected in
Santa Clara County
Prime Farmland in my Area of Interest constitutes
6% of the Bay Area total Prime Farmland
Economic benefit estimate
Additional irrigation estimates
Estimate of agricultural resilience
Policies affecting agricultural land in your Area of Interest
Only 5% of Prime Farmland in the
Bay Area is permanently protected
22. Carbon is sequestered from
the atmosphere and is
stored in biomass of trees
Carbon is stored in
the organic matter
of soils
Development and
tilling can release the
carbon stored in soils
Land use change can
release above ground
live carbon
26. Data Used for Agriculture
• Ag cover – Farmland Mapping and Monitoring Program
http://www.conservation.ca.gov/dlrp/fmmp
• Production value – Agricultural Commissioners’ annual reports
https://www.cdfa.ca.gov/exec/county/countymap/
• Land protection – Bay Area Protected Areas Database
• Irrigation deficit due to climate change – ?
• Fallow rates
• Agricultural policies
31. What’s in the Greenprint?
Prime Farmland Farmland of Statewide
Importance
Unique Farmland
Farmland of Local
Importance
Suitable Rangeland
“Best” combination
of physical and
chemical
characteristics for
the production of
crops
Meets strict criteria
“Good”
combination of
physical and
chemical
characteristics for
the production of
crops
Land that is
important to the
local economy due
to its productivity
or value
Has been used for
the production of
specific high
economic value
crops, but does not
meet Prime or
Statewide criteria
Land on which the
existing vegetation,
whether grown
naturally or through
management, is
suitable for grazing
or browsing of
livestock

32. Biodiversity
What’s in the Greenprint?
Conservation Lands
Network: Priority Land
Conservation Lands
Network: Key Riparian
Corridor
Avian Tidal Habitat
Prioritization
Habitat Connectivity Hotspots of Species
Requiring Compensatory
Mitigation
Baylands, Wetlands and
Vernal Pools
1M acres of land

answers “where
should the next
million be?”
An inventory of
riparian corridors

survival of
anadromous fish
and other aquatic
life
A prioritization of
existing tidal
habitats for 5
representative
species of bird
Regionally-scaled
large landscape
blocks and the
habitat linkages to
connect them, plus
estimates of
connectivity (from
Omniscape)
Areas of overlap
where regulated
species have their
most needed
habitat
Wet areas are
essential to
terrestrial and
aquatic life
33. What’s in the Greenprint?
Natural Land in the
Active River Area
Floodplains Hydrogeologically
Vulnerable Areas
Recharge Runoff Drinking Water
Source Watersheds
Natural land cover
in the active river
area filters excess
sediment and
pollutants thereby
maintaining or
enhancing water
quality
Natural lands in
flood hazard zones
can help reduce
flood risk for
populations and
agriculture
downstream
Natural land cover
provides some
protection to
aquifer water
quality by
decreasing
contaminant
release and
increasing
groundwater
recharge in these
areas
Recharge rates in
mm/year based on
a 30-year average
Runoff rates in
mm/year based on
a 30-year average.
High runoff means
increased delivery
of pollutants and
sediment
Natural lands in
water supply
sources deliver
cleaner water at
lower costs by
filtering the water
Water Resources
There is a lot of data in the Greenprint, more than we have time to go through today, plus I want to leave time for questions. So I chose to focus this time on some key innovations that we're getting out there through the Greenprint.
This is what we chose to focus on. Obviously there's more to see, and we encourage you to explore on your own.
For each of the themes, however, we’ll briefly show you what’s in the Greenprint and how climate change and policies are woven throughout.
For biodiversity, we are going to focus on corridors and connectivity. This is the concept that connected habitats are better for plants and wildlife than disconnected habitats.
Habitat linkages connect large landscape blocks.
