sources





Predation
Habitat Loss
Land Area




~165 million acres lost (area
size of Texas)
Includes ~1/3 monarch

High Level Working Group –
continue to coordinate US
monarch strategy
NRCS – Private lands monarch
conservation; focus on milkweed
planting in central US; Farm Bill
incentives
USGS – Powell Center
demographic model to target
restoration areas; tool in April.
USFS – Posted monarch strategic
framework. Population
assessment, enhancing seed
mixes, improving pollinator
habitat, conserving 250,000 ac
habitat.
NPS – Inventoried NPS capacity,
estimates 20 monarch projects
FY15, more for FY16; will be
integrated into “pollinator
corridors”; phase out
neonicotinoid use by 2016
EPA – Re-evaluating pesticides
and impacts to pollinators

3 - Seed
Development
Maintain regional
milkweed diversity
To provide more seed:
 Harvest native milkweed
seeds – by hand
 Grow native milkweeds
 Produce seeds, plants
 Distribute to partners
(nurseries, commercial seed
companies, schools, organizations)
5 Projects funded:
1) Lady Bird Johnson
Wildflower Center
2) NRCS PMC, TAMU
Kingsville
3) NRCS PMC, TPWD, WCDs,
TAMU, private landowners
4) NRCS PMC Oklahoma

Genus: Asclepias
Linnaeus 1753
Family: Apocynaceae
Asclepias = Greek God
of Healing

100+ spp in North
America
 ~50 with monarch use
Desert Southwest:
Most needed milkweed is:
 A. angustifolia, A. subulata, A.
asperula (313, M313, 321, 322)
 A. oenotheroides (321)
Texas
milkweeds

37 native
milkweed species
3 main species:
Asclepias asperula
Asclepias oenotheroides
Asclepias viridis
Goals:
1) provide alternatives to
planting non-native
milkweed species ecotypes
in grassland restoration
2) get these adapted
ecotypes, while they still
exist, into conservation
plantings.
Texas
milkweeds
Ecotypes – no
broader than Gould’s
Provide seeds who want to
grow these very specific
ecotypes that are adapted to
their area.
Oklahoma


OK: 25 spp
Asclepias viridis – green
milkweed
A. viridiflora – green-flowered
milkweed
A. verticillata – whorled
milkweed
A. amplexicaulis – clasping
milkweed
A. syriaca – common milkweed,
most widely available

milkweeds

NM: 28 spp
3 Native species selected as
most appropriate for NM
growing conditions:
A. speciosa – yielded
copious seed in 3rd growing
season;
A. latifolia – produces
many flowers, but paucity of
seed pods, even by 3rd
season;
A. asperula – produced low
vigor seedlings, had low
survival in the field.

management methods using past
plant survey data
2) BMPs to benefit monarchs,
pollinators, and other rare species
in migratory area
3) Ideal seed plantings for
