Although he was never an outdoorsman or sportsman on Theodore Roosevelt's scale, his growth of the national systems was comparable.[12] When Franklin was Governor of New York, the Temporary Emergency Relief Administration was essentially a state-level predecessor of the federal Civilian Conservation Corps, with 10,000 or more men building fire trails, combating soil erosion and planting tree seedlings in marginal farmland in the state of New York.[208] As President, Roosevelt was active in expanding, funding, and promoting the National Park and National Forest systems.[209] Their popularity soared, from three million visitors a year at the start of the decade to 15.5 million in 1939.[210] The Civilian Conservation Corps enrolled 3.4 million young men and built 13,000 miles (21,000 kilometres) of trails, planted two billion trees, and upgraded 125,000 miles (201,000 kilometres) of dirt roads. Every state had its own state parks, and Roosevelt made sure that WPA and CCC projects were set up to upgrade them as well as the national systems.
