Sandstone and shale formed on the ocean floor end of the Cretaceous period (approx. 60 million year ago) rose at an accelerated rate over the last several million years and at the same time severely corroded. As a result the Ikawa Forest Station boasts one of the country\u2019s highest sediment yields and the sediment movement here is more active than any other university-owned field in Japan. A debris avalanche occurs virtually every year, and research is conducted on erosion control and topography that make use of this phenomenon. The movement of the forest\u2019s soil and water is surveyed in exercises for acquiring knowledge and skills regarding the forest\u2019s function and usage. We measure the effects climate change, changes in forest vegetation, and deforestation have on micro weather systems and soil movement, as well as carbon and nitrogen circulation. Topography and erosion control engineering research is also often conducted here.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1962,"yearClosed":null,"relatedSites":null,"siteName":"Ikawa Forest Station","shortName":"Ikawa","siteType":"Stationary land-based site","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-06\/DJI_0987_0.JPG","alt":"Ikawa Forest Station in the Higashigouchi River Watershed, a tributary of the Oi River"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":9.6,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":2350.5,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":null,"biome":"mixed_forest","ecosystemType":[{"label":"Mixed Forest","uri":null}],"eunisHabitat":[{"label":"Woodland, forest and other wooded land (G)","uri":null}],"landforms":null,"geoBonBiome":["Fresh water rivers","Terrestrial"],"geology":null,"hydrology":null,"soils":null,"vegetation":null},"geographic":{"boundaries":null,"coordinates":"POINT (138.22504 35.340144)","country":["Japan"],"elevation":{"avg":1676.89,"min":2407.1,"max":900.54,"unit":"msl"},"size":{"value":1760.96,"unit":"ha"},"relatedLocations":null},"focusDesignScale":{"experiments":{"design":"partly experimentation","scale":"plot scale"},"observations":{"design":"partly observation","scale":"plot within catchment"},"observedProperties":[{"label":"biological parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20940"},{"label":"ecosystem parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20939"},{"label":"water parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20945"}]},"infrastructure":{"accessibleAllYear":false,"accessType":"dirt road  (4WD)","allPartsAccessible":false,"maintenanceInterval":null,"permanentPowerSupply":false,"operation":{"permanent":false,"notes":null,"siteVisitInterval":null},"notes":null,"collection":[{"label":"Data services","uri":null},{"label":"Intermittent","uri":null},{"label":"Lodging at site","uri":null},{"label":"Snow clearing equipment","uri":null}],"data":{"policy":{"url":null,"rights":null,"notes":null}}},"relatedResources":null,"projectRelated":{"lter":{"lterSiteClassification":"Emerging Site"}}}}
