Dear teachers,
could you please explain to me what is th meaning of "but if" in the following text:
"The prairie is sometimes called a sea of grass—a metaphor that points to the endless green expanse and the wavelike motion of the grasses. But if there is also a tide in these grasslands—a cycle of growth that sweeps chronologically across the Flint Hills. High tide comes early in the year. The prairie swells into life in early spring, and if fire comes then, the plants respond with a redoubled burst of growth. The fires clear away last year's plant debris, letting in more light and warming the soil".
Thank you in advance,
G.
