Poa compressa is native to W Eurasia. It is infrequent in China and is perhaps present only as an introduction in C to E Russia and China. It is distinguishable by its strong rhizome system, long, open sheaths, compressed culms and nodes, and scabrid-angled panicle branches. It is a good soil binder in riparian habitats. It is expected in Heilongjiang because it is frequent on the Russian side of the Chinese border.

More info for the term:
cool-seasonCanada bluegrass is an introduced, perennial, cool-season, erect,
sod-forming grass. Culms are solitary or loosely tufted, flattened, and
10 to 24 inches (25-60 cm) tall. The inflorescence is a compressed
panicle [

More info for the terms:
density,
fire regime,
grassland,
rhizomeDuring grassland fires, the fire front passes quickly and temperatures 1
inch (2.5 cm) below the soil surface rise very little [
5]. Located a
couple of inches below the soil surface, Canada bluegrass rhizomes
survive and initiate new growth after aboveground plant portions are
consumed by fire. Although the plant survives because of soil-insulated
rhizomes, postfire plant vigor and density are greatly affected by
phenological stage at time of burning (see Fire Effects On Plant).
Information regarding the importance that seedling establishment plays
in Canada bluegrass immediate postfire recovery was not found in the
literature. Postfire growth is assumed to be primarily due to rhizome
survival.

Fire Management Considerations

More info for the terms:
cool-season,
warm-seasonAnnual or biennial late spring burning can be used to control Canada
bluegrass and promote the growth of warm-season grasses in the Midwest.
The timing of burning is critical and should take place just prior to
the resumption of warm-season grass growth. Such burning favors
warm-season grasses because they are dormant at the time of burning.
Conversely, cool-season species like Canada bluegrass are harmed by late
spring fire because they resume growth in the early spring and are thus
actively growing at the time of burning [
15].

由Fire Effects Information System Plants提供
More info for the term:
associationCanada bluegrass is unable to compete with other grasses on good soils
and generally develops best on soils of low fertility or poor drainage
[
12,
25]. It has moderate drought and salinity tolerances but is not
shade tolerant [
8,
12,
30]. It grows about anywhere Kentucky bluegrass
grows but only achieves dominance on soils that are too acid, droughty,
or nutrient-deficient for Kentucky bluegrass dominance [
18]. It grows
on disturbed sites in innumerable habitats across North America. In the
Pacific Northwest, Canada bluegrass is commonly found in association
with wheatgrasses (Agropyron spp.) and hairgrasses (Deshampsia spp.),
and often grows in pure stands on poor soils [

More info for the term:
herbaceousPlant phenological stage at time of burning greatly influences fire
damage to herbaceous plants. In general, as new foliage of perennial
grasses reaches full development major food reserves have been depleted,
so that plants are injured most from fires occurring at this time [

Late spring fires, after plants have been growing for about a month or
more, appear to be the most damaging to Canada bluegrass.

Importance to Livestock and Wildlife
(
英語

由Fire Effects Information System Plants提供
Canada bluegrass is good forage for cattle, horses, and sheep [
3,
25].
It has favorable curing properties; horses pastured on Canada bluegrass
in the autumn and early winter maintain their condition [
12]. In South
Dakota it is seldom abundant enough to be a principal forage but is
important to livestock because of its wide distribution [
18].
In the Rocky Mountains, Canada bluegrass may be a valuable winter,
spring, and fall forage for elk [
20]. Mule deer consume it lightly in
the spring [
21].
Bluegrass leaves and seeds are eaten by numerous species of small
mammals and songbirds, and may form an important part of the diet of the
cottontail rabbit and wild turkey [
3,
22]. Prairie chickens eat small
amounts of the seeds [
3].

Canada bluegrass is palatable to livestock from early spring until late
fall [

succulent. Because it matures later than Kentucky bluegrass (Poa
pratensis) and is drought tolerant, it remains relatively palatable
during the summer [

Plant Response to Fire
(
英語
)
由Fire Effects Information System Plants提供
More info for the terms:
density,
fire frequency,
frequencySeason of burning and frequency of burning greatly influence Canada
bluegrass postfire recovery. Dormant-season fires favor Canada
bluegrass, and biomass and density may increase during postfire year 1.
Late spring burning, when plants are actively growing, reduces biomass
and density during postfire year 1, but biomass and density may return
to preburn levels within 1 or 2 years. Thus Canada bluegrass often
recovers within 1 or 2 years after a single late spring fire, but
density and biomass are progressively reduced if burned annually or
biennially in late spring.
In abandoned fields in southern Wisconsin, Canada bluegrass flowering
stem density was reduced 50 percent when burned annually in May for 5
years. Conversely, flowering stem density increased 170 and 440
percent following 5 years of annual burning in March or October,
respectively [
4]. A similar study in southern Wisconsin found that 3
years of annual burning in mid-May reduced Canada and Kentucky bluegrass
flowering stem density by 70 percent, while late March or early April
burning had little affect on flowering [
14].
In a reconstructed tallgrass prairie in Illinois, bluegrass (Poa
compressa and P. pratensis combined) percent relative biomass decreased
as fire frequency increased in two communities as follows [
11]:

May 10, 1962
**sampled at the end of the 1962 growing season
In oak (Quercus spp.) woods and goldenrod (Solidago spp.) fields
accidently burned between April 6 and May 2 in south-central New York,
Canada bluegrass frequency increased from 6 to 17 percent and 56 to 81
percent, respectively, 10 to 26 months after burning [
28].
After early May prescribed burning in seral brushfields in northern
Idaho, Canada bluegrass recovered rapidly on lightly burned plots.
During the first postfire growing season, it produced the bulk of grass
biomass on lightly burned plots, which was 135 pounds per acre (151
kg/ha). In comparison, grass production on heavily burned and control
plots averaged only 0.7 and 10.2 pounds per acre (0.8 and 11.4 kg/ha),
respectively [

roadsides, road cuts and fills, borrow pits, dam sites, and recreational
areas. It is often seeded with legume mixtures for revegetation of
mined areas. It is often slow to establish but once established
provides good cover and long-term growth. The performance of seeded
Canada bluegrass in mined-land reclamation has been summarized [

Zusammengedrücktes Rispengras
(
德語
)
由wikipedia DE提供
Das Zusammengedrückte Rispengras (Poa compressa), auch als Platthalmrispe oder Flaches Rispengras bezeichnet, ist ein weit verbreitetes Süßgras (Poaceae). Ein besonderes Merkmal dieser Pflanze sind seine hohlen, seitlich abgeflachten und damit im Querschnitt ovalen Halme, worauf das Art-Epitheton compressa Bezug nimmt.
Verbreitung und Standort
Das Zusammengedrückte Rispengras ist von Europa bis zum westlichen Sibirien und vom Mittelmeerraum mit Nordafrika bis China verbreitet.[1] Es kommt vom Flachland bis in Höhen von 1860 m (Alpen) vor. Es wurde nach Nordamerika eingeführt und ist dort als „Canada Bluegrass“ bekannt. In Deutschland kommt das Gras zerstreut bis häufig vor. Es fehlt streckenweise im Norden. Es wächst vor allem in Pioniergesellschaften auf Dämmen, auf Mauern, in Kiesgruben, auf Schuttplätzen und an Wegen auf offenen, trockenen und mageren, meist kalkreichen, aber humus- und feinerdearmen Sand-, Kies- und Steinböden.
Nach Ellenberg ist es eine Volllichtpflanze, subozeanisch verbreitet, ein Trockniszeiger, ein Basen- und Kalkzeiger, stickstoffarme Standorte bevorzugend. Das Zusammengedrückte Rispengras ist auch eine Ordnungscharakterart Halbruderaler Pionier- und Halbtrockenrasen (Elymetalia (=Agropyretalia) repentis) und kommt z. B. im Poo-Tussilaginetum oder im Poetum ancipiti-compressae vor. Es gedeiht aber auch im Gesellschaften der Ordnung Corynephoretalia.[2]

Merkmale
Das Zusammengedrückte Rispengras ist eine steife und graugrüne, ausdauernde Pflanze, die Wuchshöhen zwischen 10 und 40, zuweilen bis zu 70 Zentimetern erreicht. Der sommergrüne Hemikryptophyt wächst locker horstig und breitet sich über drahtige Rhizome aus. Die glatten und seitlich zusammengedrückten und damit im Querschnitt ovalen Halme wachsen vom Grund an knickig aufsteigend. Sie tragen vier bis sechs Knoten. Die glatten Blattscheiden sind ebenso zusammengedrückt, gekielt und daher zweischneidig. Die weißen Blatthäutchen (Ligulae) sind stumpf und werden 0,5 bis 4 Millimeter lang. Die starren Blattspreiten sind schmal linealisch, oberseits rau und in eine kapuzenförmige Spitze auslaufend. Neben der Blattrippe befindet sich je eine Rinne (Skispur). Die Blätter erreichen weniger als 6 Zentimeter Länge. Der Blattgrund ist stets unbewimpert.
Die Blütenstände sind kompakte, schmal pyramidenförmige Rispen. Diese messen 1,5 bis 10 Zentimeter in der Länge und zwischen 0,5 und 3 Zentimetern in der Breite. Sie sind grün, gelbgrün oder purpurn gefärbt. Die leicht eckigen und rauen Rispenäste stehen in Paaren oder Büscheln. Die drei- bis zehnblütigen, bis zu 8 Millimeter langen Ährchen stehen ihrerseits dicht büschelig an den Rispenästen. Sie sind eiförmig bis elliptisch geformt und zusammengedrückt. Alle Spelzen sind unbegrannt, gekielt und an den Kielen rau. Die dreinervigen Hüllspelzen sind etwas ungleich geformt. Die Deckspelzen sind undeutlich fünfnervig, kahl, schwach behaart oder zuweilen am Grund wollig behaart. Die Karyopsen werden von den verhärteten Deck- und Vorspelzen fest umschlossen. Die Blütezeit erstreckt sich von Juni bis August.
Die Chromosomenzahl beträgt 2n = 35, 42, 45, 49, 50, 56.[2]
Systematik
Man kennt zwei Unterarten:
-
Poa compressa subsp. compressa : Ährchen 3-6(-7)-blütig.
-
Poa compressa subsp. langiana (Rchb.) Hegi (als Art: Poa langiana Rchb.): Diese Unterart, die sich durch 7-11-blütige Ährchen und nicht behaarte Deckspelzen unterscheidet, wurde bisher nur vom Isteiner Klotz im südlichen Baden-Württemberg bekannt. Sie ist heute verschollen.[2]
Ökologie
Das Zusammengedrückte Rispengras ist ein ausdauernder Hemikryptophyt (einschließlich der Zweijährigen) und ein Kriechpionier. Die Samen verbreiten sich durch den Wind als Ballonflieger, auch Fortpflanzung durch Apomixis ist nachgewiesen. Vegetative Vermehrung erfolgt durch unterirdische Ausläufer.
Nutzung, Gefährdung und Status
In Mitteleuropa ist es als Futter- oder Weidegras ohne Bedeutung, kann aber zur Berasung trockener Böschungen eingesetzt werden. Das Zusammengedrückte Rispengras ist in Europa nicht gefährdet und genießt keinen gesonderten gesetzlichen Schutz (CITES, Berner Konvention, BArtSchV).
In Nordamerika hat das Gras einigen Wert als Weidegras auf armen und trockenen Böden. In einigen Staaten der USA, vor allem Wisconsin, gilt das Gras jedoch als invasive beziehungsweise potenziell invasive Art (Virginia, New England). So dringt es beispielsweise in Prärien und andere natürliche oder renaturierte Grasländer ein. Aufgrund seines kräftigen Rhizomwachstums und der effektiven Samenausbreitung werden negative Auswirkungen auf die natürlichen Artenzusammensetzungen (Verdrängung der heimischen Flora) sowie weitere direkte und indirekte ökologische Auswirkungen auf die Lebensgemeinschaften oder Biotope befürchtet.[3][4][5]

Plat beemdgras (Poa compressa) is een grijsgroene, overblijvende plant, die behoort tot de grassenfamilie (Poaceae). De plant komt van nature voor in Eurazië en is van daaruit verspreid naar Noord- en Zuid-Amerika en Australië.
De plant wordt 20-80 cm hoog en vormt kruipende, witte wortelstokken. De vier- tot zesknopige, opstijgende, scherpe of stomp tweekantige stengel is van boven sterk afgeplat en aan de voet geknikt. De bladscheden zijn sterk samengedrukt. De bovenste bladscheden zijn meestal langer dan het blad. Het tongetje is 1-2 mm lang.
Plat beemdgras bloeit in juni en juli met grijsgroene, smalle, tot 10 cm lange pluimen. De takken zijn kort en stijf. In de onderste kransen staan één tot vier takken bij elkaar. De 5,7 mm lange aartjes hebben drie tot zes bloempjes. De kelkkafjes en kroonkafjes zijn ongeveer 2,6 mm lang. De onderste kroonkafjes hebben geen of weinig haarwolharen en de gedroogde onderste kroonkafjes hebben geen uitspringende nerven.
De vrucht is een graanvrucht.
De plant komt voor op oude muren, langs wegen en op droge, kalkhoudende, stenige grond.

Berggröe
(
瑞典語
)
由wikipedia SV提供
Berggröe eller berggro (Poa compressa) är ett gräs, vars strå är starkt tillplattat, vilket är anledningen till compressa i det vetenskapliga namnet.
Berggröe nöjer sig med mager mark, växer t o m i bergsprickor, därav namnet. Marken kan gärna vara något sur med pH 5,5—6,5. På mager mark är den invasiv, det vill säga sprider sig lätt och konkurrerar ut andra växter, och klassas därför ibland som ogräs. På god mark klarar sig andra växter bättre mot utslagning. Förökning sker med rottrådar och frön, varav det går 5,5 miljoner på ett kg.[1]
Detta gräs är allmänt i hela Europa utom längst i söder, och finns i stora delar av Afrika, Asien och Australien. I Nordamerika är det inte ursprungligt, vilket man ett tag trodde, utan har importerats från Europa. Nu har berggröe spritt sig till Kanada och hela USA, inklusive Alaska och Hawaii, men exklusive Florida.
Berggröe är värdefullt som foder till såväl boskap som vilda djur, både stora och små.
