Sureste

Sureste Regional Park protects the gypsum steppe and river valley landscapes of southeastern Madrid, encompassing approximately 31,550 hectares of habitats along the lower courses of the Jarama and Manzanares rivers, together with stretches of the Henares and Tajuña, as they converge south of the capital. ^[1] The park preserves one of the few remaining examples of the gypsum steppe ecosystem that once characterized much of central Spain's semi-arid terrain—a globally rare habitat type that has been largely destroyed by urban expansion and agricultural conversion. Despite its position within Madrid's urban periphery, the park maintains significant ecological values including over 120 wetland areas covering more than 400 hectares.

The steppe areas support populations of great bustard, little bustard, and pin-tailed sandgrouse—species of continental steppe that find one of their last refuges near a major European capital. ^[1] The river corridors support otter, kingfisher, and diverse waterbirds. Lesser kestrel colonies occupy buildings in surrounding villages.

Gypsum-specialized vegetation communities dominate the non-riverine areas, with species adapted to the extreme salinity and aridity of gypsum soils—many found only on this rare substrate. ^[1] The river valleys support gallery woodland of poplar, tamarisk, and elm, creating green corridors through the steppe landscape.

The gypsum outcrops are Miocene evaporite deposits formed when a shallow inland sea evaporated in central Spain millions of years ago. ^[1] The gypsum creates distinctive white, eroded badlands landscapes with specialized soils that support unique vegetation communities found almost exclusively on this rare substrate.

Continental Mediterranean climate with hot dry summers exceeding 38 degrees Celsius, cold winters with regular frost, and only 350-400 millimeters of annual rainfall—conditions creating the semi-arid steppe character.

Historical activities included gypsum quarrying for construction, livestock grazing on the steppe, and irrigated agriculture in the river valleys. The area's progressive incorporation into Madrid's expanding urban zone continues to threaten remaining natural habitats.

Designated a Regional Park in 1994 by Law 6/1994 of 28 June, to protect remaining natural habitats from the urban sprawl consuming southeastern Madrid. ^[1] The park faces ongoing challenges from infrastructure development and land use pressure along its boundaries.

River corridor walks along the Jarama provide birdwatching and nature observation within sight of Madrid's skyline. The gypsum steppe areas offer stark landscape beauty in their white eroded terrain. The great bustard observation areas attract specialist birders. ^[1]

Immediately accessible from Madrid's southeastern suburbs, with multiple access points from surrounding municipalities. Interpretation centers provide information about the steppe and river ecosystems. The park's urban edge location makes it one of Europe's most accessible examples of steppe habitat. ^[1]

Defending the park boundaries from encroaching urban development represents the primary management challenge, with ongoing pressure from infrastructure projects and illegal land-use changes. Steppe bird conservation requires maintaining the open grassland character against both development and natural succession to scrub. Water quality improvement in the rivers supports the park's aquatic ecosystems. ^[1]
