Totara-matai forests are an under-represented forest type in Westland, relative to their original extent, and require protection and enhancement where possible. This study examined the regeneration of totara on gorsecovered river terraces of the Whataroa and Waiho Rivers, on a site grazed by cattle at Whataroa, and ungrazed sites at both locations. Totara is regenerating prolifically at all sit...

[1] The Longitudinal Valley fault is a key element in the active tectonics of Taiwan. It is the principal structure accommodating convergence across one of the two active sutures of the Taiwan orogeny. To understand more precisely its role in the suturing process, we analyzed fluvial terraces along the Hsiukuluan River, which cuts across the Coastal Range in eastern Taiwan in the fault’s hangin...

Abstract. A proposed null hypothesis for fluvial terrace formation is that internally generated or autogenic processes, such as lateral migration and river-bend cutoff, produce variabilities in channel incision lead to the abandonment of floodplain segments terraces. Alternatively, terraces have potential record past environmental changes from external forcings include temporal sea level hydroc...

Detailed description of the geology, topography and terraces of the Danube Bend was presented in Chapter 3. “Traditional” terrace ages concerning this area were derived from “relevant” data of the neighbouring valley sections, as lack of datable material prevented the Danube Bend terraces from setting up a more reliable chronological frame. Application of a new dating method was necessary to qu...
