Did you know?: 

In shortgrass and mixed-grass prairies, Buchloe dactyloides is one of the most important forages for livestock and wildlife. It is also rated "superior" for controlling erosion. Historically, it was the primary grass used in the sod houses of prairie settlers.

What does this species look like?

Buffalograss is a perennial grass, growing 2 to 8 inches tall or more. IIt can be erect or mat-forming by producing new plants at the end of runners (stolons) that can root nearby. Most commonly, male and female flowers are separate and occur on different plants, but on occasion they can occur on the same plant separately or rarely, in the same flower. The green flowers are tiny and inconspicuous. Male flowers are typically clustered on one to five comb-like branches arranged along a stem; female flowers are typically clustered and hidden in a small, green sheath at the top of a stem. Flowers are pollinated by wind or by self-pollinated.

Buffalograss occurs on upland portions of semi-desert grasslands, mixed-grass, shortgrass prairie, and tallgrass prairie as well as pinyon-juniper, mesquite, ponderosa pine, and oak-hickory woodlands. It occurs on all soil types, but prefers clay soils. This species is drought-, heat-, and cold-resistant. It is somewhat shade tolerant, but intolerant of dense shade.

Why observe this species?

Buffalograss is a USA-NPN regional plant species. Regional species are ecologically or economically important and are distributed more locally than calibration species. The NPN integrates these observations to better understand plant responses within the different geographic regions of the nation.

Special Considerations for Observing

If drought seems to be the cause of leaf withering for a plant, please make a comment to that effect.

This species has separate male and female flowers. If you know whether the flowers you are observing are male or female (or both), please make a comment to that effect.

Which phenophases should I observe?
Leaves

Do you see...?

Initial growth
New growth of the plant is visible, either as new green shoots sprouting from nodes on existing stems, or new green shoots breaking through the soil surface. For each shoot, growth is considered "initial" until the first leaf has unfolded. More...

Leaves
One or more live unfolded leaves are visible on the plant. A leaf is considered "unfolded" when it unrolls slightly from around the stem and begins to fall away at an angle. Do not include dried or dead leaves. More...

Flowers

Do you see...?

Flower heads
One or more fresh flower heads (inflorescences) are visible on the plant. Flower heads, which include many small flowers arranged on spikelets, emerge from inside the stem and gradually grow taller. Do not include heads whose flowers have already opened and have all wilted or dried.

How many fresh flower heads are present?

Less than 3

3 to 10

More than 10

More...

Open flowers
One or more open fresh flowers are visible on the plant. A flower is considered "open" when reproductive parts (male anthers or female stigmata) can be seen protruding from the spikelet. Do not include flowers with wilted or dried reproductive parts that remain on the plant.

How many fresh flowers are open?

Less than 3

3 to 10

More than 10

More...

Pollen release
One or more flowers on the plant release pollen when gently shaken or blown.

How many flowers release pollen?

3 to 10

Fruits

Do you see...?

Fruits
One or more fresh fruits are visible on the plant.

How many fresh fruits are present?

Ripe fruits
One or more ripe fruits are visible on the plant.

How many fruits are ripe?

Less than 3

3 to 10

More than 10

More...

Recent fruit drop
One or more fresh mature fruits or seeds have dropped or been removed from the plant since your last visit. Do not include obviously immature fruits that have dropped before ripening, such as in a heavy rain or wind.

How many mature fruits have dropped?

Less than 3

3 to 10
