I am on pg 23 and have another dense paragraph in spanish-can u help?

Question

En espanol: Las estadísticas de lo registrado señalan cifras mínimas a mediados de los `80 y ya para los `90 comienzan a entrar barcos del exterior y se amplía el comercio de la isla por ser el principal abastecedor de la región, que ya era un enclave forestal dominado por las compañías colonizadoras.

My (slightly nonsensical) translation:
The registered statistics indicate a minimum average during the ‘80s and ‘90s outside ships began to enter and the commerce of the island extended to be the main supplier of the region, that or was a forest enclave dominated by the colonizing companies.

Answer 1

The registered statistics indicate a minimum average figures during the mid 80s and for the 90s foreign ships began to enter, and the commerce of the island extended because it was the main supplier of the region, at that time it was a forest enclave dominated by the colonizing companies.

Answer 2

The registered statistics indicate minimum figures by the mid 80's an only by the 90's outside ships began to enter and the commerce of the island expanded because it was the main supplier of the region, which already was a forest enclave dominated by the colonizing companies.
