Vedado de Robres: Los Monegros (Huesca) Aragn. Espaa.Familia: FAGACEAEDistribucin: Magreb y en Europa, solo en la Pennsula Ibrica, donde se distribuye por gran parte de la misma aunque enrareciendose en el W y en Portugal; en Aragn est ampliamente extendido por el Sistema Ibrico, los Somontanos del Prepirineo y ms localizada en las Sierras Exteriores, donde cede paulatinamente el terreno a Q. cerrioides. En la Depresin del Ebro aparece puntualmente en la Sierra de Alcubierre y algn otro resalte montaoso.Hbitat: El quejigo forma bosques por lo general de poca extensin o aparece en pequeos grupos salpicando el mbito de los carrascales; Con un requerimiento ecolgico de mayor frescor y humedad y suelo ms profundo que el que necesita la carrasca, encontramos el quejigo en la Depresin del Ebro rehuyendo los ambientes ms ridos en laderas umbras y a cierta altitud, por ejemplo en la Sierra de Alcubierre; Por el contrario, en los Somontanos y el Prepirineo, aparece en resaltes soleados u otros enclaves protegidos trmicamente; en el Sistema Ibrico se encuentra en el piso supramediterrneo donde forma tambin pequeos bosquetes. Los quejigales han visto muy mermadas y alteradas sus pobalciones debido a la explotacin humana, por lo que es de suponer una mayor presencia en condiciones naturales y, de hecho, se observa cierta recuperacin de la especie en muchas zonas de nuestra regin.Preferencia edfica: Basfila Calccola. En nuestro territorio se comporta como calccola preferente, aunque parece ser indiferente a la naturaleza del sustrato en otras regiones.Rango altitudinal: 800- 1500 mFloraci: ( Marzo ) Abril - Mayo ( Junio )Fructificacin: Septiembre - OctubreForma Biolgica: Macrofanerfito caducifolioExtractado del Atlas de la Flora de Aragn (Herbario de Jaca)

Quercus agrifoliacoast live oak. Twenty or so years ago I was pulling weeds near my property when I spied a small seedling near a rotting stump. On the spur of the moment I decided to give the seedling a chance. It has now grown into a lovely small tree that I hope will shade people after I'm gone. I say "I hope" because about three years ago a neighbor hacked away at this tree and a small one near by because he said it ruined his "view". The smaller tree was so hacked up that it died but this one survived. To make matters worse, It just so happens that the "view" the neighbor wished to protect is of a nondescript Berkeley street. I have no idea what will happen to my tree in the future even if it survives Sudden Oak Death syndrome for it is on a public right-of-way where decisions will be made by bureaucrats. The tree has been producing acorns for a few years now. This year it has a particularly large amount of catkins. Photographed in Berkeley, CA.

Parque grande. Zaragoza: Aragn (Espaa)Cultivado.Familia: FAGACEAEDistribucin: W de Asia, hasta los Urales y por casi toda Europa; en la Pennsula Ibrica por la mitad N y alcanza el C en Somosierra, pero su ptimo se encuentra en la cornisa cantbrica entre Galicia y Navarra y, ya muy localizado, en las zonas ms hmedas del Pirineo cataln; en Aragn solo en el extremo occidental del Moncayo donde muestra su lmite suroriental en el Sistema Ibrico. Hbitat: Los nicos ejemplares conocidos de Aragn, se encuentran en el sector nororiental del Moncayo y aparecen como rboles aislados o en pequeos grupos, mezclados con otros robles, salpicando el hayedo o entre las repoblaciones de pino silvestre. Ya en la parte soriana, junto al barranco de Castilla y ocupando pequeos promontorios rocosos, pueden verse algunos pequeos grupos rodeados por el hayedo que parece haber relegado al roble a un ambiente mucho ms reducido y sobrio del que probablemente debi ocupar.Preferencia edfica: Acidfila. En sustratos silceos y por lo general en suelos profundos, frtiles, con humedad permanente e incluso encharcamiento temporal; Sin embargo, las poblaciones del Moncayo aparecen a veces sobre suelos pedregosos que se ajustan poco a las exigencias normales de la especie.Rango altitudinal: ( 900 ) 1200- 1400 ( 1500 ) mFloracin: Abril - JunioFructificacin: Septiembre - OctubreForma Biolgica: Macrofanerfito caducifolioExtractado del Atlas de la Flora de Aragn (Herbario de Jaca)

2011-10-26 Lower Austria, district Neunkirchen - mixed forest (670 msm Quadrant 8362/4).Pinus nigra is not native to this habitat (and neither is Picea abies), and Pinus sylvestris only would grow here in small numbers (as it is less competitive here than e. g. beech): this should be a beech forest by habitat, and there are indeed a few beeches present.

This is one of my favorite stands of Quercus gambelii. This clone is on a north-facing slope and therefore receives a little more moisture and shade allowing it to become somewhat more aborescent than the scrub oak forms that are more exposed higher on the ridge above (with even taller, arborescent oaks present in the drainage at the bottom of this slope). A portion of the oaks just above this, i.e. to the right of this view) and closer to the ridge were burned about twelve years ago (from a lightning strike) but these plants were not directly impacted by that event. The plants are slow growing and their ability to expand vegetatively is a big part of their success although new plants do germinate from acorns and have been observed on the adjoining slope, but seedling survival rate (as with many/most plant species) is low. Because they spread via rhizomes it is difficult to determine how old a given clone might be. Individuals are thought to be able to live for 150+ years. But the clone it is connected to persists for a much longer time (assuming it is isn't damaged by the activities of people). USGS images show that this and adjoining clones were at this precise location in Feb. 1970 and they really have not changed/expanded much in the past 43 years. Some individuals then in this clone are conservatively probably at least 75 years old and probably much more; Gambel's oak clones have been likely growing on this slope for thousands of years.To the credit of some of the residential development (and residents) in the Olympus Cove area including around Oakridge Elementary, some significant stands of Gambel's oak have been preserved. Below the shoreline levels, however, they have been mostly not as well preserved yet they make excellent landscape plants. When found in suburbia, they should be retained and not exterminated. Digging should not occur within a wide perimeter around them.Gambel's oak is highly variable and while it can grow in completely open places, it tends to like a little bit of protection from the elements.
