Residential development has impacted a significant amount of the harbour foreshores over many years. Much of what remained was preserved partly due to the presence of military bases, and partly because of the work of conservationists. Early conservationists were responsible for stopping mining at Ashton Park in the 19th Century.[citation needed] Other places were saved because of people such as Niels Neilsen, who became the New South Wales Minister for Lands and a strong advocate of a public reserve around Sydney Harbour.[citation needed] Nielsen was ahead of his time when he used the phrase "national park" in regard to the harbour foreshores, but Sydney eventually caught up with him.
