*Stratum 2: Oklahoma Panhandle Playa Lakes (matrix stratum)*

[]{.mark}

Stratum 2 includes all areas in BMR 109 that make up the playa lakes
matrix in western Oklahoma. Ecologically known as the High Plains, this
is largely the panhandle of Oklahoma. It includes all or parts of
Cimarron, Texas, Beaver, Harper, and Ellis Counties. All of the focal
species in the BMR occur in the stratum. Type 1 habitat is made up of
playa wetlands (also called playa lakes or prairie potholes) which are
small, seasonally wet wetlands of an indeterminate number. These playa
wetlands are small (average about 17 acres in size) and are often
separated from the next nearest wetland/playa by several miles. The
majority of herbaceous wetlands in the Short Grass Prairie Region are
found in these playa wetlands. Type 2 habitat is made up of seasonal
wetlands that occur in the flood plains of various streams and the
Beaver and Cimarron rivers. These flood plain wetlands often form small
complexes of strings of wetlands tied together along the flood plain.
Additional Type 2 habitat is any other small lakes, ponds, and
artificially created wetlands, such as flooded rice fields or sod farms.
Survey methods have not been designed for the stratum but are expected
to vary widely among the survey areas. Type 1 and Type 2 habitat
includes state and federal ownership, but is mostly privately owned so
gaining access will require careful planning.

*Stratum 2: Canadian River Corridor (matrix stratum)*

[]{.mark}

Stratum 2 is made up of the habitat along the Canadian River in BMR 110
that is not in designated sites or in other matrix strata. Some to all
of the focal species in the BMR likely occur in the stratum. Type 1
habitat includes wetland habitat of the Canadian River floodplain. The
Canadian River flows southeastward across the state through BMRs 110 &
111, is part of the Arkansas River Basin, is characterized by broad,
shallow, and sandy channels. Type 2 habitat is made up of riparian
wetlands along the smaller tributaries and branches of the Canadian,
including the North Canadian and Deep Fork of the Canadian Rivers.
Survey methods have not been designed for the stratum but are expect to
vary widely among the survey areas. Ownership and access issues are
unknown.

*Stratum 3: Cimarron River Corridor (matrix stratum)*

[]{.mark}

Stratum 3 is made up of the habitat along the Cimarron River that is not
in designated sites or in other matrix strata. Some to all of the focal
species in the BMR likely occur in the stratum. Type 1 habitat includes
wetland habitat along the Cimarron River which is a part of the Arkansas
River Basin in north-northwestern Oklahoma. The Cimarron River corridor,
similar to that of the Canadian, is also characterized by broad,
shallow, and sandy channels. Type 2 habitat is made up of riparian
wetlands along the smaller tributaries of the Cimarron. Survey methods
have not been designed for the stratum but are expect to vary widely
among the survey areas. Ownership and access issues are unknown.

[]{.mark}

*Stratum 4: Red River Corridor (matrix stratum)*

[]{.mark}

Stratum 4 is made up of the habitat along the Red River within BMR 110
that is not in designated sites or in other matrix strata. Some to all
of the focal species in the BMR likely occur in the stratum. Type 1
habitat includes wetland habitat along the Red River and its chief
tributaries, which are the North Fork, Washita, Blue, Boggy, and
Kiamichi Rivers. Although the Red River flows through BMRs 110, 111, and
113 and forms the southern state boundary of Oklahoma, the river is
thickest in BMR 110. Type 2 habitat is made up of riparian wetlands
along the smaller tributaries of the Red River. Survey methods have not
been designed for the stratum but are expected to vary widely among the
survey areas. Ownership and access issues are unknown.

[]{.mark}

*Stratum 5: West-Central Oklahoma (matrix stratum)*

[]{.mark}

Stratum 5 includes all areas in BMR 110 that are not in designated sites
or other matrix strata. Some to all of the focal species in the BMR may
occur in the stratum. Type 1 habitat is made up of overlooked
lakes/reservoirs, ponds, and wetland areas. It is difficult to gauge how
much Type 2 habitat exists. Survey methods have not been designed for
the stratum but are expected to vary widely among the survey areas.
Habitat is mostly privately owned so gaining access will require careful
planning.

*Stratum 2: Canadian River Corridor (matrix stratum)*

[]{.mark}

Stratum 2 is made up of the habitat along the Canadian River in BMR 111
that is not in designated sites or in other matrix strata. Some to all
of the focal species in the BMR likely occur in the stratum. Type 1
habitat includes wetland habitat along the Canadian River, which flows
southeastward across the state through BMRs 110 & 111, and is part of
the Arkansas River Basin. The Canadian River corridor is characterized
by broad, shallow, and sandy channels. The Canadian River floodplain
near the town of Norman, Oklahoma may support average numbers of
shorebirds during migration. Type 2 habitat is made up of riparian
wetlands along the smaller tributaries and branches of the Canadian,
including the North Canadian and Deep Fork of the Canadian Rivers.
Survey methods have not been designed for the stratum but are expect to
vary widely among the survey areas. Ownership and access issues are
unknown.

[]{.mark}

*Stratum 3: Flint Hills Region (matrix stratum)*

Stratum 3 includes all areas in the Flint Hills uplands that are not in
designated sites or other matrix strata. Some of the focal species in
the BMR likely occur in the stratum. Type 1 habitat includes lake and
river-associated wetland habitat found in the grasslands of the Flint
Hills. Type 2 habitat is any other small lakes, ponds, and wetlands. The
Flint Hills are mostly in Kansas but occupy a small portion of north BMR
111, where they merge with the Osage Hills in Oklahoma. The amount of
water available for aquatic birds is difficult to gauge and most likely
differs from year to year. Survey methods have not been designed for the
stratum but are expect to vary widely among the survey areas. Ownership
and access issues are unknown.

*Stratum 4: Red River Corridor (matrix stratum)*

[]{.mark}

Stratum 4 is made up of the habitat along the Red River within BMR 111
that is not in designated sites or in other matrix strata. Some to all
of the focal species in the BMR likely occur in the stratum. Type 1
habitat includes wetland habitat along the Red River and its chief
tributaries, which are the North Fork, Washita, Blue, Boggy, and
Kiamichi Rivers. The Red River flows through BMRs 110, 111, and 113 and
forms the southern state boundary of Oklahoma. Type 2 habitat is made up
of riparian wetlands along the smaller tributaries of the Red River.
Survey methods have not been designed for the stratum but are expected
to vary widely among the survey areas. Ownership and access issues are
unknown.

[]{.mark}

*Stratum 5: East-Central Oklahoma (matrix stratum)*

[]{.mark}

Stratum 5 includes all areas in BMR 111 that are not in designated sites
or other matrix strata. Some to all of the focal species in the BMR may
occur in the stratum. Type 1 habitat is made up of overlooked
lakes/reservoirs, ponds, and wetland areas. It is difficult to gauge how
much Type 2 habitat exists. Survey methods have not been designed for
the stratum but are expected to vary widely among the survey areas.
Habitat is mostly privately owned so gaining access will require careful
planning.

*Stratum 2: Arkansas River Corridor (matrix stratum)*

[]{.mark}

Stratum 2 is made up of the habitat along the Arkansas River in BMR 112
that is not in designated sites or in other matrix strata. Some to all
of the focal species in the BMR likely occur in the stratum. Type 1
habitat includes wetland habitat along the Arkansas River, which flows
southeastward across the eastern-most part of Oklahoma (BMRs 112 & 113).
The Arkansas River northwest of Tulsa (near Osage, Oklahoma) attracts
shorebirds during migration in moderate to low numbers. Additional Type
1 habitat includes riparian wetlands along the chief tributaries of the
Arkansas River, which are (excluding the Cimarron and Canadian rivers
from the west, which are already in other matrix strata), the Verdigris,
Grand, and Illinois rivers from the north and northeast, and the Poteau
River from the south. Type 2 habitat is any other small lakes, ponds,
and wetlands, including artificially created ones such as flooded rice
fields or sod farms. Survey methods have not been designed for the
stratum but are expect to vary widely among the survey areas. Type 1 and
Type 2 habitat includes state and federal ownership, but is mostly
privately owned so gaining access will require careful planning.

*Stratum 3: Northeast Oklahoma (matrix stratum)*

[]{.mark}

Stratum 3 includes all areas in BMR 112 that are not in designated sites
or other matrix strata. Some to all of the focal species in the BMR
likely occur in the stratum. Type 1 habitat includes any overlooked
lakes, city reservoirs, creek/river corridors, and the wetland habitat
or marsh along their borders. Not much Type 2 habitat exists. Survey
methods have not been designed for the stratum but are expect to vary
widely among the survey areas. Ownership includes state and federal, but
is mostly tribal and private so gaining access will require careful
planning.

*Stratum 4: Southeast Oklahoma (matrix stratum)*

[]{.mark}

Stratum 4 includes all areas in BMR 113 that are not in designated sites
or other matrix strata. All of the focal species in the BMR likely occur
in the stratum. Southeastern Oklahoma is made up of several different
ecological regions that provide habitat for marsh and shorebirds,
including prairie, oak hickory forests, bottomland hardwood forests
(with and without moist soil), pine savanna, and cypress swamps.
Therefore, Type 1 habitat is made up mudflats, emergent marshes,
shallow-water impoundments, riparian wetlands, and bottomland hardwoods.
Some of what has been described as Type 1 habitat may actually be Type 2
habitat, depending on how often it harbors species of interest. Survey
methods have not been designed for the stratum but are expect to vary
widely among the survey areas. Ownership and access issues are unknown.
