bridges, and over 10,000 trees and shrubs added. By 2003, fish had increased from 63 to 80 fish per of stream and a new species, lamprey, was found. Pests Since the land was reserved (from 1905 onwards), the fringe areas and lower slopes have slowly regenerated after suffering light logging, fires, pigs, goats, possums, cats, hedgehogs, rats, mice, stoats, weasels and ferrets, with occasional deer and wallaby. Goats, possum and rats are controlled, with possum self-resetting traps trialled in 2011. About of privately owned forest adjoin the reserve, some of which is protected by covenant. Kauri dieback disease is not present, so a boot cleaning station was put at the Huntly end in 2015. Fire is also a threat. In 2017 an area of 600 by 300m on a ridge beside the quarry was burnt. Quarry The large quarry at 181 Waingaro Road, Ngāruawāhia, opened in a quarry reserve in 1948 and now goes well below sea-level. It was bought by Brian Perry Ltd in the 1980s and sold to Fulton Hogan in 2016. An extension which would have doubled the size of the quarry wasn't permitted in 2008. It would have taken native trees estimated to be 800 years old. The quarry then employed 13 and supplied about 35% of the area's needs. Environment Waikato granted Perry Aggregates resource consents in 2009, following which bait stations were put in the area in 2011 and the quarry was given Mimico Environmental Awards for that and, in 2018, for extending native fish passage. Tracks The range has been used for recreational rambling since at least 1892. There are two main walkways through the range, allowing excellent views of the Waikato Plains below. The main one is Hakarimata Walkway (12 km, 7 hr 30 min) along the ridge from Parker Road at the northern end to the Hakarimata Rail Trail (off Waingaro Rd) at the south. Te Araroa follows that walkway to the summit, where a viewing tower offers vistas towards the coast, across the Waikato Basin and to Ruapehu on a clear day. Te Aroroa drops from the summit by the other main walkway, Hakarimata Summit Track (2 km, 3 hr return, 335 metres on 1349 steps), to Brownlee Avenue in Ngāruawāhia. The steps had 140,000 visits in 2016, compared to 5000 in 2011, shortly after they opened. The remainder of the track south to Hakarimata Rail Trail (3.5 km, 2
