Before the typhoon, their farm had a total of 50 trees + 30 trees = <<50+30=80>>80 trees.
If there was 1 more than Mahogany than Narra tree that fell, then this means there were 2 Narra trees and 2 + 1 = 3 Mahogany trees that fell during the typhoon.
So, Bea's mom planted 2 trees x 2 = <<2*2=4>>4 Narra trees.
She also planted 3 trees x 3 = <<3*3=9>>9 Mahogany trees.
So, her mom planted 4 trees + 9 trees = <<4+9=13>>13 more trees.
After the typhoon, they only had 80 trees - 5 trees = <<80-5=75>>75 trees left.
Therefore, there are 75 trees + 13 trees = <<75+13=88>>88 trees now.
