Dit bestand bevat houtsingels die onderdeel zijn van het meetnet houtsingels. Elke vier jaar worden deze houtsingels gemonitord. De status van de houtsingels wordt bepaald door luchtfoto vergelijking. Doel is om inzicht te krijgen in o.a. de effectiviteit van het beleid ten behoud van houtsingels.<\/SPAN><\/P>

In Westerwolde, het Gorecht en in het landschap van het Zuidelijk Westerkwartier komen houtsingels en houtwallen voor. Zij dragen bij aan de afwisseling en het contrast tussen de open en besloten gebieden en daarmee aan de diversiteit van het landschap. Het zijn lijnvormige beplantingen met bomen en/of struiken. Deze elementen vormen vaak begrenzingen van percelen of zijn afscheidingen met een andere functie. Grofweg kunnen twee typen worden onderscheiden: beplantingen die op een kunstmatige aarden wal staan (houtwal) en beplantingen die op dezelfde hoogte staan als het omringende land (houtsingel).<\/SPAN> Een deel van de houtsingels uit dit bestand is onderdeel van het meetnet wat betekent dat deze elke vier jaar worden gemonitord. Van de overige houtsingels is de status onbekend.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": "esriGeometryPolyline", "sourceSpatialReference": { "wkid": 28992, "latestWkid": 28992,
