I contracted the barren hills in the village to plant seedlings. Is there any subsidy for returning farmland to forests?

What you said does not belong to the scope of returning farmland to forests.

First, the scope of returning farmland to forests

Returning farmland to forests refers to sloping farmland and desertified farmland with serious soil erosion and low and unstable yield. Its standards are: mountainous areas and hilly areas; Sloping farmland with serious soil erosion, low and unstable grain yield, slope above 6 degrees and contracted or extended by farmers; Plain areas; Sandy farmland contracted by farmers with serious wind and sand hazards, low and unstable grain output. As long as conditions permit and farmers are willing, the scale of returning farmland to forests should be expanded and as much as possible.

Slope farmland and sandy wasteland that are not contracted to households and fallow are not included in the scope of returning farmland to forests, and can be used for afforestation in barren hills.

Second, there can be subsidies.

Afforestation subsidy standards for barren hills, wasteland and desert only subsidize seedlings and afforestation fees, and 50 yuan is subsidized once per mu.
