*Stratum 2: Southwestern Texas (matrix stratum)*

[]{.mark}

Stratum 2 includes all areas in BMR 114 that make up southwestern Texas
that are not in designated sites. Some of the focal species in the BMR
occur in the stratum. Type 1 habitat is made up of man-made reservoirs
or lakes and any riparian-associated wetland habitat, such as along the
Upper Rio Grande River. Not much Type 2 habitat exists. 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 is mostly privately
owned so gaining access will require careful planning.

are from websites of several Audubon chapters in Texas and the Texas
Ornithological Society. The species list was based on 1 checklist from
the region.

**Bird monitoring region 115: Texas-Short Grass Prairie**

This region covers the Short Grass Prairie region of Texas.
Approximately 46 aquatic species occur at least commonly, at some time
of year, in the region (Table 3); 7 designated sites and 2 matrix strata
have been identified (Fig. 3, Table 4).

prairie river-associated wetlands (i.e. the Red and Canadian Rivers and
their tributaries, which run through BMRs 115, 116, 119, and 121),
saline lakes, man-made reservoirs, stock ponds, and associated wet
meadows. 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 is mostly privately owned so gaining access will require careful
planning.

*Stratum 3: Northeastern Texas (matrix stratum)*

Stratum 3 includes all areas in BMR 116 that are not included in
designated sites or other matrix strata. Some of the focal species in
the BMR occur in the stratum. Type 1 habitat is made up of man-made
reservoirs or lakes and any wet meadows associated with rivers and
streams. Not much Type 2 habitat exists. 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 is mostly privately owned so
gaining access will require careful planning.

were available for this region so 8 checklists from Oklahoma (BMR 110)
was used for the initial checklist.

**Bird monitoring region 117: Texas-Edwards Plateau**

This region covers the Edwards Plateau region in central Texas.
Approximately 47 aquatic species occur at least commonly, at some time
of year, in the region (Table 7); 2 designated sites and 2 matrix strata
have been identified (Fig. 5, Table 8).

*Stratum 2: Lower Rio Grande Valley (matrix stratum)*

[]{.mark}

Stratum 2 is made up of the Lower Rio Grande Valley in south Texas that
are not in designated sites. All of the focal species in the BMR likely
occur in the stratum. Type 1 habitat is made up of Rio Grande oxbows or
other riparian-associated wetlands, saline lakes, man-made reservoirs
and city water treatment ponds, and stock ponds with associated
wetlands. Type 2 habitat includes roadside bodies of water (i.e. El
Zacatal, La Sara, Delta Lake, Llano Grande Lake), other small lakes,
ponds, mudflats along coastal roads, and small wetland areas. 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 is mostly
privately owned so gaining access will require careful planning.

*Stratum 3: South Texas (matrix stratum)*

[]{.mark}

Stratum 3 includes all areas in BMR 118 that are not included in
designated sites or other matrix strata. All of the focal species in the
BMR likely occur in the stratum. Type 1 habitat is made up of man-made
reservoirs or lakes and any wet meadows associated with rivers and
streams. Not much Type 2 habitat exists. 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 is mostly privately owned so
gaining access will require careful planning.

**Bird monitoring region 119: Texas-Oaks and Prairies**

This region covers the Oaks and Prairies region of Texas. Approximately
22 aquatic species occur at least commonly, at some time of year, in the
region (Table 11); 14 designated sites and 1 matrix stratum have been
identified (Fig. 7, Table 12).

*Stratum 2: North-Central Texas (matrix stratum)*

[]{.mark}

Stratum 2 includes all areas in BMR 119 that are not included in
designated sites or other matrix strata. All of the focal species in the
BMR likely occur in the stratum. Type 1 habitat is made up of man-made
reservoirs or lakes and any wet meadows associated with rivers and
streams. Not much Type 2 habitat exists. 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 is mostly privately owned so
gaining access will require careful planning.

***Sources***: Cecilia M. Riley, Gulf Coast Bird Observatory. Site names
are from websites of several Audubon chapters in Texas and the Texas
Ornithological Society. The species list was based on 1 checklist from
the region.

**Bird monitoring region 120: Texas-Gulf Coastal Prairie**

This region covers the Gulf Coastal Prairie region of Texas.
Approximately 92 aquatic species occur at least commonly, at some time
of year, in the region (Table 13); 26 designated sites and 1 matrix
stratum have been identified (Fig. 8, Table 14).

*Stratum 2: Texas Gulf Coast Wetlands (matrix stratum)*

[]{.mark}

Stratum 2 includes all areas in BMR 120 that are not included in
designated sites or other matrix strata. All of the focal species in the
BMR likely occur in the stratum. Type 1 habitat is made up of coastal
wetlands. Type 2 habitat includes other small lakes, ponds, mudflats
along coastal roads, or riparian-associated wetland habitat. 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 is mostly
privately owned so gaining access will require careful planning.

are from websites of several Audubon chapters in Texas and the Texas
Ornithological Society. The species list was based on 5 checklists from
the region.

**Bird monitoring region 121: Texas-West Gulf Coastal Pl/Ouachitas**

This region covers the west Gulf Coastal Plain and Ouachitas region of
Texas. Approximately 37 aquatic species occur at least commonly, at some
time of year, in the region (Table 15); 6 designated sites and 2 matrix
stratum have been identified (Fig. 9, Table 16).

*Stratum 2: Katy Prairie (matrix stratum)*

[]{.mark}

Stratum 2 is made up of the areas of the Katy Prairie of eastern Texas
that are not in designated sites or other matrix strata. All of the
focal species in the BMR likely occur in the stratum. Type 1 habitat is
made up of agricultural rice fields (converted from native grassland)
which are flooded periodically. These rice fields are artificial
wetlands, and they provide important habitat for water birds. Type 2
habitat is any other small lakes, ponds, and small wetland areas, such
as those created by creek and river beds.. 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 is mostly privately owned so
gaining access will require careful planning.

[]{.mark}

*Stratum 3: Eastern Texas (matrix stratum)*

[]{.mark}

Stratum 3 includes all areas in BMR 121 that make up eastern Texas that
are not in designated sites or other matrix strata. All of the focal
species in the BMR likely occur in the stratum. Type 1 habitat is made
up of man-made reservoirs or lakes and any riparian-associated wetland
habitat, such as along the Missouri River. Not much Type 2 habitat
exists. 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 is mostly privately owned so gaining access will require careful
planning.

are from websites of several Audubon chapters in Texas and the Texas
Ornithological Society. No checklists were available for this region so
4 checklists from Oklahoma (BMR 113) was used for the initial checklist.
