The answer is in the question. Fire must be harmful to them. Pine trees, and other conifers have high levels of substances called turpines in their leaves. This serves two maior purposes, to make them taste foul (few animals graze on pine leaves) and to act as a kind of anti-freeze, so the leaves work all year round, even in subarctic conditions.
However, turpines are highly flammable, so pine saplings will rarely survive a grassland fire. The saplings don't survive on the grassland and the trees don't encroach.

Pine trees are not typically found in savanna ecosystems, which are characterized by grasslands with scattered trees. Savannas usually support species that are adapted to dry conditions and periodic fires, such as acacias and baobabs.

Instead, they thrive in different habitats, such as forests and mountainous regions.
