My mother accidentally burned the grass on the field ridge, burning half of the forest. There are about 3 or 4 acres of land and 200 to 300 trees. What should be done legally?

The crime of fire refers to an act that causes a fire due to the fault of the perpetrator, causing serious consequences and endangering public safety. This is the crime of negligent endangerment of public safety. Anyone who commits the crime of setting fire shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years; if the circumstances are minor, he shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention.

The situation you added is not clear enough. Let me briefly explain the specific standards for conviction and sentencing, and you should be able to understand:

The Supreme Court has not set a unified standard for the seriousness of fire crimes. The "Standards of the State Forestry Administration and the Ministry of Public Security on the Jurisdiction and Filing of Criminal Cases concerning Forests and Terrestrial Wildlife" stipulates that if a fire causes a forest fire, causing a forest fire area of ??more than 2 hectares, or causing serious injury or death, it will cause a forest fire area of ??10 hectares. If the forest area is more than 50 hectares, or if more than 2 people die, it is a particularly serious case. The other is the regulations formulated by the Provincial High Court based on the actual situation of the province. For example, the "Several Regulations on Handling Fire and Fire Liability Accident Cases" jointly formulated by the Jiangxi Provincial Higher People's Court, the Provincial People's Procuratorate, and the Provincial Public Security Department, which was implemented on February 1, 2007, stipulates: (1) If the fire is caused by negligence, in accordance with According to the second paragraph of Article 115 of the Law, the offender shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years. or 10 hectares of protective forest and special-purpose forest; 6. Although casualties, household burning, and direct property losses are less than the prescribed amount, the circumstances are serious and cause great damage to production, teaching, and life. (2) Anyone who causes a fire negligently and falls under any of the following circumstances shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention in accordance with the "minor circumstances" stipulated in Paragraph 2 of Article 115 of this Law: 1. Causing the death of more than one person or 3 or more people were seriously injured; 2. Direct property losses of more than 300,000 yuan were caused; 3. More than 15 households were burned down and direct property losses totaled more than 250,000 yuan; 4. The fire prevention forest area was more than 2 hectares.

I don’t know which province you are from, but they are basically the same in every province. You can compare.
