Thank you for posting your question here at brainly. <span>Two types of treatments: type of seed and fire. </span>
<span>Type of seeds: 1. Known seed type that requires fire. 2. Known seed that is killed by far. 3. Experimental/unknown seed. </span>
<span>Fire treatments: 1. No fire. 2. Fire. </span>
